Okay

Difference of 2 squares, difference of 2 cubes, and sum of 2 cubes

And you can factor with substitution

I don’t know how the cubes work and I’m interested to know

Also I never learned how to do it wth substitution, is it really just a bunch of trial and error or

some black pro-segregationists argued that. because, if you look at the number, somehow blacks under jim crow succeed financially and in school much better compared to black in current time.

cubes is just similar to square. similar process. you'll learn it in grade 12 (at least according to the ontario curriculum)

unsure if this is what you're asking for, but Khan academic is helpful: https://www.khanacademy.org/math/algebra/x2f8bb11595b61c86:quadratics-multiplying-factoring/x2f8bb11595b61c86:factor-quadratics-strategy/a/factoring-quadratics-in-any-form

part of me thinks it’s something like (x + 3)(x-6)(x+3)

well, kinda?

the standard way is this:

I know 54 isn't a perfect square but

oh so both terms are squares?

the other way, you'd have to do some testing with number combinations

when you factor them out, in one bracket

so when you distribute them the ab cancel but a and b get raised to 3 I assume

is a calculator helpful on this since my math teacher told me grade 12 is 1/4 no calculator

if my math isn't bad it will be a^3 - a^2b + a^2b + ab^2 - ab^2 + b^3

yeah. you'll learn the trick. it's also depends on the teacher. For advance functions, my teacher allow calculators, but for calculus and vectors, we don't

yeah. once you expand most terms cancel out except for a^3 + b^3

so are you doing examples where you are given a but not b

does it work with a^3 - b^3

I don't wanna write the equation again

you mean "a^3 + (blank)^3 = (a + *blank*) (a^2 - a*blank* + blank^2)

yea

idk but it doesn't sound too bad once I get the hang of it

yup. if you refer back to the original image, the red sign is opposite to the original operation.

it shouldn't be too hard. function & advance function are very easy.

I know some of my classmates are already studying on grade 12 stuff or something

i can't remember if we ever have a *blank* situation that i just depicted. but we would probably have an equivalent equation in different forms that us to find b and/or subtitute b with a related equation to a

oh yeah. my vietnamese friends came over already learning all this stuff

like 2 of my classmates know 100 digits of pi

How useful is factoring perfect cubes btw

I was surprised on how useful factoring is in the first place

most of what you learn in class isn't applicable in real life, i think 😂 . but maybe i'm bias. i'm not in a field that requires heavy math, so i can't speak to all fields.

That is all.

*physics ptsd itches up again*

Ok

Hey

Perfect cubes as in 9x^2 - 49?
