My totally serious guide to solving quadratic equations ✨

Sorry not sorry

I don't feel like writing rn, I feel like doing math🥰 so come

(Note = I used to take IGCSE Additional math and ext math soooo i hope this hepls if ur taking the same thing LOL)

(also pls don't unfollow i promise i wont be a full math blog 😔)

EXAMPLE =

x² + 4x + 4 = 0

ax² + bx + c

So as you can see there is a secret, hidden 1 in front of the x² so that will be our a value. For the b value you can get it in front of the x which is 4 and lastly the c is the number at the end with no variable so its 4.

TLDR; a = 1, b = 4, c = 4

So I usually make a big X thing and i put the product of a and c at the top and put the b value at the bottom. Like the pic above ig

So the product of a and c is 4 x 1 so it's 4 and then the b is just 4 so its 4.

THEN we gotta find 2 numbers that can be added to become 4 and mutliplied to become 4

SO it has to be like this (pretend the numbers are m and n)

m + n = 4

m × n = 4

So now we gotta do guess and check, I usually try to find the factors of the product, the one we have rn is 4 so

Factors of 4 are 1, 2 and 4

So let's try to find it! Let's try to check if 4 and 1 can.

1 + 4 = 5 ❌ <- doesn't add up to 4

2 + 2 = 4 ✅ <- adds up to 4

So now we just put it into the factors thing, Your answer should be (x+2)(x+2) or (x+2)²

BUT WAIT We're not done yet!

We gotta find x

So since it's (x+2) multiplied by (x+2) that means x + 2 = 0

and we just solve algebraically

x + 2 = 0

x = -2

So there's your answer

OR You could always use the

AND THEN WE JUST KEEP ON WINNING ????

I don’t understand why people say Papas Bakeria is the hardest Papas game

That’s the easiest game for me

The hardest ones are Freezeria and Cupcakeria •<•

So yesterday one of my colleagues said that we all just cycle through 3 conversation topics so what are your three topics? I think mine are the importance of Swedish-Danish relations on Dutch history, the sims and twilight (unfortunately)

Well, we know what Crowley was doing in ancient Athens, I guess: tempting some poet into starting a blasphemous dining club

dyscalculia strikes again. I was tearing my hair out over my accounts not balancing because I couldn't figure out why the fuck I had a deficit of almost $10k for my debit accounts... turns out that in the very first part of that question, I dropped a zero from an account balance. I fixed that and the entire thing was magically balancing. for fuck's sake.

History of Math has been a hysterical class if only because we get to hear about the beef

hey bro sorry to bother you bro but i heard you say that modern art is bullshit bro but it's just that the art you've been taught to perceive as such by society and school is limited to paintings bro don't worry the meaning is still there bro you can see it too if you stop bitching about how you could paint like that too bro it's not your fault that contemporary and performance art is made inaccessible and hard to understand to those outside of their circles bro just take my hands and i can show you

(sliding beads along my abacus) I mean no matter how you slice it I'm going to have time to draw something for all of my birdmutuals. Let's be generous and say that I have like 15 of them. I think a third of them will not care enough to put out a list, another handful will forget to do it, which means realistically I think I'm going to end up in the ballpark of maybe like. 7. I feel like 30 minutes is plenty of time to drawr a little gift or something. so let's say max case scenario. 12 birdmutuals submit lists. I could knock that out easily in 3 days.

That sure sounds like something bad is going to happen to these teens just doing their homework.

Had some wine feeling good made a really shitty bowl in ceramics class this morning that I’m really worried has a bunch of air holes in it and had a really crappy therapy session where I didn’t talk too much but was honest about some other stuff which is good overall I guess but now I’m doing drunk crochet and watching the Duggar family documentary and probably going to stop watching soon once they start talking about the awful stuff but yeah day in the life of a woman doing her best I guess

trigonometry makes me want to bang my head on the table. repeatedly

tbh the only reason why I'm not skipping every math lesson and actually giving it ago is bc I know Alan Turing would be disappointed

In the deleted scene where Kane is getting breakfast, he doesn’t put the lids back on the containers of food or put them away after he uses them. Now, either this was an acting decision made by John Hurt to imply that the food containers were going to be left out for the other crew mates to use, or the man had something affecting his executive functioning ability and that’s just how he made breakfast.
