quadratic equations
ax ^ 2 + bx + c = 0
quadratic formula
x = [- b +- (b ^ 2 - 4ac) ^ 1 / 2] / 2a
power equations
if x ^ n = k
odd n
x = k ^ (1 / n)
even n
if x ^ 2 = k
x = 0
k = 0
no real solutions
k < 0
x = +- k ^ ( 1 / 2)
k > 0
factored form
( x - a )( x + b ) = 0
null factor law
if ab = 0, then a = 0 or b = 0
product
ab
sum
(a + b)
