Solution for F(x)=(7-4x)(0.5x+3) equation: 


Simplifying
F(x) = (7 + -4x)(0.5x + 3)

Multiply F * x
xF = (7 + -4x)(0.5x + 3)

Reorder the terms:
xF = (7 + -4x)(3 + 0.5x)

Multiply (7 + -4x) * (3 + 0.5x)
xF = (7(3 + 0.5x) + -4x * (3 + 0.5x))
xF = ((3 * 7 + 0.5x * 7) + -4x * (3 + 0.5x))
xF = ((21 + 3.5x) + -4x * (3 + 0.5x))
xF = (21 + 3.5x + (3 * -4x + 0.5x * -4x))
xF = (21 + 3.5x + (-12x + -2x2))

Combine like terms: 3.5x + -12x = -8.5x
xF = (21 + -8.5x + -2x2)

Solving
xF = 21 + -8.5x + -2x2

Solving for variable 'x'.

Reorder the terms:
-21 + 8.5x + xF + 2x2 = 21 + -8.5x + -2x2 + -21 + 8.5x + 2x2

Reorder the terms:
-21 + 8.5x + xF + 2x2 = 21 + -21 + -8.5x + 8.5x + -2x2 + 2x2

Combine like terms: 21 + -21 = 0
-21 + 8.5x + xF + 2x2 = 0 + -8.5x + 8.5x + -2x2 + 2x2
-21 + 8.5x + xF + 2x2 = -8.5x + 8.5x + -2x2 + 2x2

Combine like terms: -8.5x + 8.5x = 0.0
-21 + 8.5x + xF + 2x2 = 0.0 + -2x2 + 2x2
-21 + 8.5x + xF + 2x2 = -2x2 + 2x2

Combine like terms: -2x2 + 2x2 = 0
-21 + 8.5x + xF + 2x2 = 0
