Solution for F(x)=x^2+4x equation:


Simplifying
F(x) = x2 + 4x

Multiply F * x
xF = x2 + 4x

Reorder the terms:
xF = 4x + x2

Solving
xF = 4x + x2

Solving for variable 'x'.

Reorder the terms:
-4x + xF + -1x2 = 4x + x2 + -4x + -1x2

Reorder the terms:
-4x + xF + -1x2 = 4x + -4x + x2 + -1x2

Combine like terms: 4x + -4x = 0
-4x + xF + -1x2 = 0 + x2 + -1x2
-4x + xF + -1x2 = x2 + -1x2

Combine like terms: x2 + -1x2 = 0
-4x + xF + -1x2 = 0

Factor out the Greatest Common Factor (GCF), 'x'.
x(-4 + F + -1x) = 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 '(-4 + F + -1x)' equal to zero and attempt to solve: Simplifying -4 + F + -1x = 0 Solving -4 + F + -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 + F + 4 + -1x = 0 + 4 Reorder the terms: -4 + 4 + F + -1x = 0 + 4 Combine like terms: -4 + 4 = 0 0 + F + -1x = 0 + 4 F + -1x = 0 + 4 Combine like terms: 0 + 4 = 4 F + -1x = 4 Add '-1F' to each side of the equation. F + -1F + -1x = 4 + -1F Combine like terms: F + -1F = 0 0 + -1x = 4 + -1F -1x = 4 + -1F Divide each side by '-1'. x = -4 + F Simplifying x = -4 + F

Solution

x = {0, -4 + F}
