Solution for F(x)=(x+7)(8x-4) equation:


Simplifying
F(x) = (x + 7)(8x + -4)

Multiply F * x
xF = (x + 7)(8x + -4)

Reorder the terms:
xF = (7 + x)(8x + -4)

Reorder the terms:
xF = (7 + x)(-4 + 8x)

Multiply (7 + x) * (-4 + 8x)
xF = (7(-4 + 8x) + x(-4 + 8x))
xF = ((-4 * 7 + 8x * 7) + x(-4 + 8x))
xF = ((-28 + 56x) + x(-4 + 8x))
xF = (-28 + 56x + (-4 * x + 8x * x))
xF = (-28 + 56x + (-4x + 8x2))

Combine like terms: 56x + -4x = 52x
xF = (-28 + 52x + 8x2)

Solving
xF = -28 + 52x + 8x2

Solving for variable 'x'.

Reorder the terms:
28 + -52x + xF + -8x2 = -28 + 52x + 8x2 + 28 + -52x + -8x2

Reorder the terms:
28 + -52x + xF + -8x2 = -28 + 28 + 52x + -52x + 8x2 + -8x2

Combine like terms: -28 + 28 = 0
28 + -52x + xF + -8x2 = 0 + 52x + -52x + 8x2 + -8x2
28 + -52x + xF + -8x2 = 52x + -52x + 8x2 + -8x2

Combine like terms: 52x + -52x = 0
28 + -52x + xF + -8x2 = 0 + 8x2 + -8x2
28 + -52x + xF + -8x2 = 8x2 + -8x2
