What is the solution set to the inequality 5(x - 2)(x + 4) > 0? A.) {x| x>-4 and x <2}
B.) {x| X <-4 or x > 2}
C.) {x| X <-2 or x>4}
D.) {x| x>-2 or x <4}

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.
