1. what are the roots of the equation? 5x^3+45x^2+70x=0 a. {−7, −2, 0} b. {−7, 0, 2} c. {0, 2, 7} d. {−2, 0, 7} 2. what number needs to be added to both sides of the equation in order to complete the square? x^2−18x=17 the file attached below is for question #2

1. factor the left side, divide all terms by 5x, solve all x's for 0

answer is A. {−7, −2, 0}

2. you would need to add (-9^2) to both sides.  -9^2 = 81, so add 81 to both sides

f-1(x)= cube root of 19x squared/x
