The equations that are true for x = -2 and x = 2 are -4 = 0 and 4
= 16
An equation is a mathematical statement that establishes the equality of two quantities.
Analysis:
Testing the equation x2 - 4 = 0
for x = 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.
