Solution for F(x)=(30-2x)(20-2x) equation: 


Simplifying
F(x) = (30 + -2x)(20 + -2x)

Multiply F * x
xF = (30 + -2x)(20 + -2x)

Multiply (30 + -2x) * (20 + -2x)
xF = (30(20 + -2x) + -2x * (20 + -2x))
xF = ((20 * 30 + -2x * 30) + -2x * (20 + -2x))
xF = ((600 + -60x) + -2x * (20 + -2x))
xF = (600 + -60x + (20 * -2x + -2x * -2x))
xF = (600 + -60x + (-40x + 4x2))

Combine like terms: -60x + -40x = -100x
xF = (600 + -100x + 4x2)

Solving
xF = 600 + -100x + 4x2

Solving for variable 'x'.

Reorder the terms:
-600 + 100x + xF + -4x2 = 600 + -100x + 4x2 + -600 + 100x + -4x2

Reorder the terms:
-600 + 100x + xF + -4x2 = 600 + -600 + -100x + 100x + 4x2 + -4x2

Combine like terms: 600 + -600 = 0
-600 + 100x + xF + -4x2 = 0 + -100x + 100x + 4x2 + -4x2
-600 + 100x + xF + -4x2 = -100x + 100x + 4x2 + -4x2

Combine like terms: -100x + 100x = 0
-600 + 100x + xF + -4x2 = 0 + 4x2 + -4x2
-600 + 100x + xF + -4x2 = 4x2 + -4x2

Combine like terms: 4x2 + -4x2 = 0
-600 + 100x + xF + -4x2 = 0
