Simplifying (z + -3)(z + 7) = 0 Reorder the terms: (-3 + z)(z + 7) = 0 Reorder the terms: (-3 + z)(7 + z) = 0 Multiply (-3 + z) * (7 + z) (-3(7 + z) + z(7 + z)) = 0 ((7 * -3 + z * -3) + z(7 + z)) = 0 ((-21 + -3z) + z(7 + z)) = 0 (-21 + -3z + (7 * z + z * z)) = 0 (-21 + -3z + (7z + z2)) = 0 Combine like terms: -3z + 7z = 4z (-21 + 4z + z2) = 0 Solving -21 + 4z + z2 = 0 Solving for variable 'z'. Factor a trinomial. (-7 + -1z)(3 + -1z) = 0Subproblem 1
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 = -7Subproblem 2
Set the factor '(3 + -1z)' equal to zero and attempt to solve: Simplifying 3 + -1z = 0 Solving 3 + -1z = 0 Move all terms containing z to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -1z = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -1z = 0 + -3 -1z = 0 + -3 Combine like terms: 0 + -3 = -3 -1z = -3 Divide each side by '-1'. z = 3 Simplifying z = 3Solution
z = {-7, 3}
