Solution for F(x)=(x+1)(x-5) equation:


Simplifying
F(x) = (x + 1)(x + -5)

Multiply F * x
xF = (x + 1)(x + -5)

Reorder the terms:
xF = (1 + x)(x + -5)

Reorder the terms:
xF = (1 + x)(-5 + x)

Multiply (1 + x) * (-5 + x)
xF = (1(-5 + x) + x(-5 + x))
xF = ((-5 * 1 + x * 1) + x(-5 + x))
xF = ((-5 + 1x) + x(-5 + x))
xF = (-5 + 1x + (-5 * x + x * x))
xF = (-5 + 1x + (-5x + x2))

Combine like terms: 1x + -5x = -4x
xF = (-5 + -4x + x2)

Solving
xF = -5 + -4x + x2

Solving for variable 'x'.

Reorder the terms:
5 + 4x + xF + -1x2 = -5 + -4x + x2 + 5 + 4x + -1x2

Reorder the terms:
5 + 4x + xF + -1x2 = -5 + 5 + -4x + 4x + x2 + -1x2

Combine like terms: -5 + 5 = 0
5 + 4x + xF + -1x2 = 0 + -4x + 4x + x2 + -1x2
5 + 4x + xF + -1x2 = -4x + 4x + x2 + -1x2

Combine like terms: -4x + 4x = 0
5 + 4x + xF + -1x2 = 0 + x2 + -1x2
5 + 4x + xF + -1x2 = x2 + -1x2

Combine like terms: x2 + -1x2 = 0
5 + 4x + xF + -1x2 = 0
