GCF

The greatest common factor, a term where you remove something that everything is multiplied by.

Example, greatest common factor of 12x³ and 18x² is 6x²

The finalized version would be 6x²(2x+3)

if it was x²+5x+6 it would be (x+2)(x+3) factored down. Think carefully about why and it will come through.

slope intercept formula

y=mx+b

y and x are random points that can be used.

m is the slope

b is the y-intercept (the point that crosses the y axis

point slope formula

y-y₁=m(x-x₁)

slope formula

m=y₂-y₁\frac x₂-x₁

PEMDAS

u should know this idiot

definition of rational exponents

this is basically where a fraction thats in the power slot can be reversed as the whatever root.

for example 125^1/3 would become 125 cubed root. the BOTTOM number of ¹/ₙ would be the part thats cubed. another example is if it was 125^2/3 but try that in your head
