Solution for (9-m)(4m-2)=0 equation:


Simplifying
(9 + -1m)(4m + -2) = 0

Reorder the terms:
(9 + -1m)(-2 + 4m) = 0

Multiply (9 + -1m) * (-2 + 4m)
(9(-2 + 4m) + -1m * (-2 + 4m)) = 0
((-2 * 9 + 4m * 9) + -1m * (-2 + 4m)) = 0
((-18 + 36m) + -1m * (-2 + 4m)) = 0
(-18 + 36m + (-2 * -1m + 4m * -1m)) = 0
(-18 + 36m + (2m + -4m2)) = 0

Combine like terms: 36m + 2m = 38m
(-18 + 38m + -4m2) = 0

Subproblem 1

Set the factor '(-9 + m)' equal to zero and attempt to solve: Simplifying -9 + m = 0 Solving -9 + m = 0 Move all terms containing m to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + m = 0 + 9 Combine like terms: -9 + 9 = 0 0 + m = 0 + 9 m = 0 + 9 Combine like terms: 0 + 9 = 9 m = 9 Simplifying m = 9

Subproblem 2

Set the factor '(1 + -2m)' equal to zero and attempt to solve: Simplifying 1 + -2m = 0 Solving 1 + -2m = 0 Move all terms containing m to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -2m = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -2m = 0 + -1 -2m = 0 + -1 Combine like terms: 0 + -1 = -1 -2m = -1 Divide each side by '-2'. m = 0.5 Simplifying m = 0.5

Solution

m = {9, 0.5}
