Solution for 8*x*4=2(x^2-5*x) equation:


Simplifying
8x * 4 = 2(x2 + -5x)

Reorder the terms for easier multiplication:
8 * 4x = 2(x2 + -5x)

Multiply 8 * 4
32x = 2(x2 + -5x)

Reorder the terms:
32x = 2(-5x + x2)
32x = (-5x * 2 + x2 * 2)
32x = (-10x + 2x2)

Solving
32x = -10x + 2x2

Solving for variable 'x'.

Combine like terms: 32x + 10x = 42x
42x + -2x2 = -10x + 2x2 + 10x + -2x2

Reorder the terms:
42x + -2x2 = -10x + 10x + 2x2 + -2x2

Combine like terms: -10x + 10x = 0
42x + -2x2 = 0 + 2x2 + -2x2
42x + -2x2 = 2x2 + -2x2

Combine like terms: 2x2 + -2x2 = 0
42x + -2x2 = 0

Factor out the Greatest Common Factor (GCF), '2x'.
2x(21 + -1x) = 0

Ignore the factor 2.

Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(21 + -1x)' equal to zero and attempt to solve: Simplifying 21 + -1x = 0 Solving 21 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-21' to each side of the equation. 21 + -21 + -1x = 0 + -21 Combine like terms: 21 + -21 = 0 0 + -1x = 0 + -21 -1x = 0 + -21 Combine like terms: 0 + -21 = -21 -1x = -21 Divide each side by '-1'. x = 21 Simplifying x = 21

Solution

x = {0, 21}
