Solution for F(x)=4x^2-12x^2-16x equation:


Simplifying
F(x) = 4x2 + -12x2 + -16x

Multiply F * x
xF = 4x2 + -12x2 + -16x

Reorder the terms:
xF = -16x + 4x2 + -12x2

Combine like terms: 4x2 + -12x2 = -8x2
xF = -16x + -8x2

Solving
xF = -16x + -8x2

Solving for variable 'x'.

Reorder the terms:
16x + xF + 8x2 = -16x + -8x2 + 16x + 8x2

Reorder the terms:
16x + xF + 8x2 = -16x + 16x + -8x2 + 8x2

Combine like terms: -16x + 16x = 0
16x + xF + 8x2 = 0 + -8x2 + 8x2
16x + xF + 8x2 = -8x2 + 8x2

Combine like terms: -8x2 + 8x2 = 0
16x + xF + 8x2 = 0

Factor out the Greatest Common Factor (GCF), 'x'.
x(16 + F + 8x) = 0

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 '(16 + F + 8x)' equal to zero and attempt to solve: Simplifying 16 + F + 8x = 0 Solving 16 + F + 8x = 0 Move all terms containing x to the left, all other terms to the right. Add '-16' to each side of the equation. 16 + F + -16 + 8x = 0 + -16 Reorder the terms: 16 + -16 + F + 8x = 0 + -16 Combine like terms: 16 + -16 = 0 0 + F + 8x = 0 + -16 F + 8x = 0 + -16 Combine like terms: 0 + -16 = -16 F + 8x = -16 Add '-1F' to each side of the equation. F + -1F + 8x = -16 + -1F Combine like terms: F + -1F = 0 0 + 8x = -16 + -1F 8x = -16 + -1F Divide each side by '8'. x = -2 + -0.125F Simplifying x = -2 + -0.125F

Solution

x = {0, -2 + -0.125F}
