What are the solutions of x^2+6x-6=10?
a. x=-8 or x=-2
b. x=-8 or x=2
c. x=1 or x=-7
d. x=-1 or x=7

A. is the answer in this question

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
