F(x) = x2 – 3x + 5 g(x) = 2x2 – 4x – 11 What is h(x) = f(x) + g(x)?

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.

and surely you know how much that is.
