Solution for x(x+1)=(x-6)(x+4) equation:


Simplifying
x(x + 1) = (x + -6)(x + 4)

Reorder the terms:
x(1 + x) = (x + -6)(x + 4)
(1 * x + x * x) = (x + -6)(x + 4)
(1x + x2) = (x + -6)(x + 4)

Reorder the terms:
1x + x2 = (-6 + x)(x + 4)

Reorder the terms:
1x + x2 = (-6 + x)(4 + x)

Multiply (-6 + x) * (4 + x)
1x + x2 = (-6(4 + x) + x(4 + x))
1x + x2 = ((4 * -6 + x * -6) + x(4 + x))
1x + x2 = ((-24 + -6x) + x(4 + x))
1x + x2 = (-24 + -6x + (4 * x + x * x))
1x + x2 = (-24 + -6x + (4x + x2))

Combine like terms: -6x + 4x = -2x
1x + x2 = (-24 + -2x + x2)

Add '-1x2' to each side of the equation.
1x + x2 + -1x2 = -24 + -2x + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
1x + 0 = -24 + -2x + x2 + -1x2
1x = -24 + -2x + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
1x = -24 + -2x + 0
1x = -24 + -2x
