x²-16=0

Question

x²-16=0

hoblos · Answer

x² = 16
x= ± 4

directrix · Answer

(x + 4)(x - 4) = 0

Use the Zero Product Property to solve

x + 4 = 0 or x - 4 = 0

x = -4 or x = 4

anonymous · Answer

Input: x^2 - 16 = 0
Alternate form: x^2 = 16
 (x - 4) (x + 4)  = 0

Solution: x = -4
x = 4

I can also give you the "Root Plot" :)
