Factor a trinomial. (-9 + -13z)(7 + -8z) = 0Subproblem 1
Set the factor '(-9 + -13z)' equal to zero and attempt to solve: Simplifying -9 + -13z = 0 Solving -9 + -13z = 0 Move all terms containing z to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + -13z = 0 + 9 Combine like terms: -9 + 9 = 0 0 + -13z = 0 + 9 -13z = 0 + 9 Combine like terms: 0 + 9 = 9 -13z = 9 Divide each side by '-13'. z = -0.6923076923 Simplifying z = -0.6923076923Subproblem 2
Set the factor '(7 + -8z)' equal to zero and attempt to solve: Simplifying 7 + -8z = 0 Solving 7 + -8z = 0 Move all terms containing z to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + -8z = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -8z = 0 + -7 -8z = 0 + -7 Combine like terms: 0 + -7 = -7 -8z = -7 Divide each side by '-8'. z = 0.875 Simplifying z = 0.875Solution
z = {-0.6923076923, 0.875}
