Do you understand why it is (a)??

OpenStudy (anonymous):

Solution to x^2-16=0 is to be computed as follows: x^2 = 16 So, x = square root of (16). Square root of 16 can have one of two values. Positive 4 and negative 4. Squaring both will result in 16. So, the answer is B.

OpenStudy (anonymous):

just square both sides of equation so.. sqrt of x^2 = x, sqrt of 16 is + or -4 so x = + or -4, B
