Question

Hich equations are true for x = –2 and x = 2? Select two options

Answer 1

Answer:

first and fourth

Step-by-step explanation:

x² - 4 = 0 ( add 4 to both sides )

x² = 4 ( take square root of both sides )

x = ± $\sqrt{4}$ = ± 2

that is x = - 2, x = 2

4x² = 16 ( divide both sides by 4 )

x² = 4 ( take square root of both sides )

x = ± $\sqrt{4}$ = ± 2

that is x = - 2, x = 2
