Factor the equation and use the Quadratic Formula to solve for x. Remember that x must be a real number. | |
How many unique real values of x solve x4 - 16 = 0?
x4 - 16 = 0
rewrite this as
(x2)2 - 42 = 0
apply difference of two squares formula, we get
(x2 - 4) (x2 + 4)
factoring, we get
(x2 - 4) = x2 - 22
so,
( x + 2) (x - 2)
so,
real factors of x are
x = 2 and x = -2
