Choose the expression that is equivalent to identity: a^2 - b^2 . a (a - b)^2
b (a + b)(a - b)
c a^2 + b^2
d (a + b)^2

A

Step-by-step explanation:

If x ^ 2 = 100, then x = 10.

 For this case what you should know is the correct clearance of the following equation:
 
 We then have two possible solutions:
 
 Rewriting we have:
 
 Therefore, the solutions are:
 
 
 A statement that is NOT true is:
 If x^2 = 100, then x = 10.
