Solution for F(x)=(2x-1)(x-4) equation: 


Simplifying
F(x) = (2x + -1)(x + -4)

Multiply F * x
xF = (2x + -1)(x + -4)

Reorder the terms:
xF = (-1 + 2x)(x + -4)

Reorder the terms:
xF = (-1 + 2x)(-4 + x)

Multiply (-1 + 2x) * (-4 + x)
xF = (-1(-4 + x) + 2x * (-4 + x))
xF = ((-4 * -1 + x * -1) + 2x * (-4 + x))
xF = ((4 + -1x) + 2x * (-4 + x))
xF = (4 + -1x + (-4 * 2x + x * 2x))
xF = (4 + -1x + (-8x + 2x2))

Combine like terms: -1x + -8x = -9x
xF = (4 + -9x + 2x2)

Solving
xF = 4 + -9x + 2x2

Solving for variable 'x'.

Reorder the terms:
-4 + 9x + xF + -2x2 = 4 + -9x + 2x2 + -4 + 9x + -2x2

Reorder the terms:
-4 + 9x + xF + -2x2 = 4 + -4 + -9x + 9x + 2x2 + -2x2

Combine like terms: 4 + -4 = 0
-4 + 9x + xF + -2x2 = 0 + -9x + 9x + 2x2 + -2x2
-4 + 9x + xF + -2x2 = -9x + 9x + 2x2 + -2x2

Combine like terms: -9x + 9x = 0
-4 + 9x + xF + -2x2 = 0 + 2x2 + -2x2
-4 + 9x + xF + -2x2 = 2x2 + -2x2

Combine like terms: 2x2 + -2x2 = 0
-4 + 9x + xF + -2x2 = 0
