Solution for x=4(x^2)-15x equation:


Simplifying
x = 4(x2) + -15x

Reorder the terms:
x = -15x + 4x2

Solving
x = -15x + 4x2

Solving for variable 'x'.

Combine like terms: x + 15x = 16x
16x + -4x2 = -15x + 4x2 + 15x + -4x2

Reorder the terms:
16x + -4x2 = -15x + 15x + 4x2 + -4x2

Combine like terms: -15x + 15x = 0
16x + -4x2 = 0 + 4x2 + -4x2
16x + -4x2 = 4x2 + -4x2

Combine like terms: 4x2 + -4x2 = 0
16x + -4x2 = 0

Factor out the Greatest Common Factor (GCF), '4x'.

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 '(4 + -1x)' equal to zero and attempt to solve: Simplifying 4 + -1x = 0 Solving 4 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + -1x = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -1x = 0 + -4 -1x = 0 + -4 Combine like terms: 0 + -4 = -4 -1x = -4 Divide each side by '-1'. x = 4 Simplifying x = 4

Solution

x = {0, 4}
