(3x-9)(4-8x)=

Solution for (3x-9)(4-8x)= equation:

Simplifying
(3x + -9)(4 + -8x) = 0

Reorder the terms:
(-9 + 3x)(4 + -8x) = 0

Multiply (-9 + 3x) * (4 + -8x)
(-9(4 + -8x) + 3x * (4 + -8x)) = 0
((4 * -9 + -8x * -9) + 3x * (4 + -8x)) = 0
((-36 + 72x) + 3x * (4 + -8x)) = 0
(-36 + 72x + (4 * 3x + -8x * 3x)) = 0
(-36 + 72x + (12x + -24x2)) = 0

Combine like terms: 72x + 12x = 84x
(-36 + 84x + -24x2) = 0

Solving
-36 + 84x + -24x2 = 0

0 + x = 0 + 3
x = 0 + 3

Combine like terms: 0 + 3 = 3
x = 3

Simplifying
x = 3
Subproblem 2
Set the factor '(1 + -2x)' equal to zero and attempt to solve:

Simplifying
1 + -2x = 0

Solving
1 + -2x = 0

Move all terms containing x to the left, all other terms to the right.

Add '-1' to each side of the equation.
1 + -1 + -2x = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -2x = 0 + -1
-2x = 0 + -1

Combine like terms: 0 + -1 = -1
-2x = -1

Divide each side by '-2'.
x = 0.5

Simplifying
x = 0.5
Solution
x = {3, 0.5}
