Simplifying (z + 5)(z + -7) = 0 Reorder the terms: (5 + z)(z + -7) = 0 Reorder the terms: (5 + z)(-7 + z) = 0 Multiply (5 + z) * (-7 + z) (5(-7 + z) + z(-7 + z)) = 0 ((-7 * 5 + z * 5) + z(-7 + z)) = 0 ((-35 + 5z) + z(-7 + z)) = 0 (-35 + 5z + (-7 * z + z * z)) = 0 (-35 + 5z + (-7z + z2)) = 0 Combine like terms: 5z + -7z = -2z (-35 + -2z + z2) = 0 Solving -35 + -2z + z2 = 0 Solving for variable 'z'. Factor a trinomial. (-5 + -1z)(7 + -1z) = 0Subproblem 1
Set the factor '(-5 + -1z)' equal to zero and attempt to solve: Simplifying -5 + -1z = 0 Solving -5 + -1z = 0 Move all terms containing z to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + -1z = 0 + 5 Combine like terms: -5 + 5 = 0 0 + -1z = 0 + 5 -1z = 0 + 5 Combine like terms: 0 + 5 = 5 -1z = 5 Divide each side by '-1'. z = -5 Simplifying z = -5Subproblem 2
Set the factor '(7 + -1z)' equal to zero and attempt to solve: Simplifying 7 + -1z = 0 Solving 7 + -1z = 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 + -1z = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -1z = 0 + -7 -1z = 0 + -7 Combine like terms: 0 + -7 = -7 -1z = -7 Divide each side by '-1'. z = 7 Simplifying z = 7Solution
z = {-5, 7}
