Question

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

Answer 1

The equations that are true for x = -2 and x = 2 are $x^{2}$ -4 = 0 and 4$x^{2}$ = 16

What is an equation?

An equation is a mathematical statement that establishes the equality of two quantities.

Analysis:

Testing the equation x2 - 4 = 0

for x = 2,  $(2)^{2}$ - 4 = 4-4 = 0

for x = -2 = (-2)2 - 4 = 4-4 = 0

Therefore x2-4 = 0 is true

Testing for 4x2 =16

for x  = 2 , 4(2) ^2 = 4x4 = 16

for x = -2 4(-2)^2 = 4(4) = 16.

All other equations are not true except these two.
