a2+30a+56=0 , solve for a Using the quadratic formula, you will find that: a=-2 , a=-28
Set up the equation and solve for z: 28 + z = 56 (next, subtract 28 from each side of the equaition to solve) z = 28

56 plus zero
x - 56 = 79 x - 56 + 56 = 79 + 56 x = 135
56 plus 1 equals 57. == ==
1 + 2 + 56 = 59
First, subtract 3x from each side of the equation. Then, divide each side of the equation by 7 .
