Simplifying (2z + -1)(3z + -2) = 0 Reorder the terms: (-1 + 2z)(3z + -2) = 0 Reorder the terms: (-1 + 2z)(-2 + 3z) = 0 Multiply (-1 + 2z) * (-2 + 3z) (-1(-2 + 3z) + 2z * (-2 + 3z)) = 0 ((-2 * -1 + 3z * -1) + 2z * (-2 + 3z)) = 0 ((2 + -3z) + 2z * (-2 + 3z)) = 0 (2 + -3z + (-2 * 2z + 3z * 2z)) = 0 (2 + -3z + (-4z + 6z2)) = 0 Combine like terms: -3z + -4z = -7z (2 + -7z + 6z2) = 0 Solving 2 + -7z + 6z2 = 0 Solving for variable 'z'. Factor a trinomial. (1 + -2z)(2 + -3z) = 0Subproblem 1
Set the factor '(1 + -2z)' equal to zero and attempt to solve: Simplifying 1 + -2z = 0 Solving 1 + -2z = 0 Move all terms containing z to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -2z = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -2z = 0 + -1 -2z = 0 + -1 Combine like terms: 0 + -1 = -1 -2z = -1 Divide each side by '-2'. z = 0.5 Simplifying z = 0.5Subproblem 2
Set the factor '(2 + -3z)' equal to zero and attempt to solve: Simplifying 2 + -3z = 0 Solving 2 + -3z = 0 Move all terms containing z to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + -3z = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -3z = 0 + -2 -3z = 0 + -2 Combine like terms: 0 + -2 = -2 -3z = -2 Divide each side by '-3'. z = 0.6666666667 Simplifying z = 0.6666666667Solution
z = {0.5, 0.6666666667}
