Simplifying (2 + -1z)(4z + 9) = 0 Reorder the terms: (2 + -1z)(9 + 4z) = 0 Multiply (2 + -1z) * (9 + 4z) (2(9 + 4z) + -1z * (9 + 4z)) = 0 ((9 * 2 + 4z * 2) + -1z * (9 + 4z)) = 0 ((18 + 8z) + -1z * (9 + 4z)) = 0 (18 + 8z + (9 * -1z + 4z * -1z)) = 0 (18 + 8z + (-9z + -4z2)) = 0 Combine like terms: 8z + -9z = -1z (18 + -1z + -4z2) = 0 Solving 18 + -1z + -4z2 = 0 Solving for variable 'z'. Factor a trinomial. (2 + -1z)(9 + 4z) = 0Subproblem 1
Set the factor '(2 + -1z)' equal to zero and attempt to solve: Simplifying 2 + -1z = 0 Solving 2 + -1z = 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 + -1z = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1z = 0 + -2 -1z = 0 + -2 Combine like terms: 0 + -2 = -2 -1z = -2 Divide each side by '-1'. z = 2 Simplifying z = 2Subproblem 2
Set the factor '(9 + 4z)' equal to zero and attempt to solve: Simplifying 9 + 4z = 0 Solving 9 + 4z = 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 + 4z = 0 + -9 Combine like terms: 9 + -9 = 0 0 + 4z = 0 + -9 4z = 0 + -9 Combine like terms: 0 + -9 = -9 4z = -9 Divide each side by '4'. z = -2.25 Simplifying z = -2.25Solution
z = {2, -2.25}
