If the difference (3x^2- 2x + 5) - (x^2- 6x - 2) is multiplied by 1/2 x 2 what is the result, written in standard form?

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.
