Question

1. Select all equations that have two solutions.

A.x² = 16
B. 4x² = 0
C. x² = -16
D. 3x + 2 = 14
Ex² - 1 = 24
F) (x + 8) (x - 8) = 0

Answer 1

The equations that have two solutions are:

A) x² = 16 (solutions: x = 4, x = -4)
B) 4x² = 0 (solutions: x = 0)
F) (x + 8)(x - 8) = 0 (solutions: x = -8, x = 8)
