sqroot(x1+x2)²+(y1+y2)²

quaderatic formula

-b± sqaureoot(b²-4ac) divided by 2a

(a+b)²

a²+ab+b²

(a+b)³

a³+a²b+ab²+b³

Real Numbers:

natural numbers

positive whole numbers

whole numbers

numbers without fractions or decimals, always positive

intergers

any type of number, no decimal or fractions, (-1, -5, 2, 6)

midpoint formula

(x1+y1/2 , x2+y2/2)

exponents

power is the small number on top, main number is the base, whole thing called exponent

properties

u^m x u^n = u^m+n | u^m / u^n = u^m-n | u^-1 = 1/u^n | (uv)^m = u^mv^m | (u^m)^n = u^mxn

circle equation

r= (x-h)² + (y-k)²

difference of 2 squares

(u+v)(u-v) = u²-v²
