Solution for F(x)=2(x-7)(x-3) equation: 


Simplifying
F(x) = 2(x + -7)(x + -3)

Multiply F * x
xF = 2(x + -7)(x + -3)

Reorder the terms:
xF = 2(-7 + x)(x + -3)

Reorder the terms:
xF = 2(-7 + x)(-3 + x)

Multiply (-7 + x) * (-3 + x)
xF = 2(-7(-3 + x) + x(-3 + x))
xF = 2((-3 * -7 + x * -7) + x(-3 + x))
xF = 2((21 + -7x) + x(-3 + x))
xF = 2(21 + -7x + (-3 * x + x * x))
xF = 2(21 + -7x + (-3x + x2))

Combine like terms: -7x + -3x = -10x
xF = 2(21 + -10x + x2)
xF = (21 * 2 + -10x * 2 + x2 * 2)
xF = (42 + -20x + 2x2)

Solving
xF = 42 + -20x + 2x2

Solving for variable 'x'.

Reorder the terms:
-42 + 20x + xF + -2x2 = 42 + -20x + 2x2 + -42 + 20x + -2x2

Reorder the terms:
-42 + 20x + xF + -2x2 = 42 + -42 + -20x + 20x + 2x2 + -2x2

Combine like terms: 42 + -42 = 0
-42 + 20x + xF + -2x2 = 0 + -20x + 20x + 2x2 + -2x2
-42 + 20x + xF + -2x2 = -20x + 20x + 2x2 + -2x2

Combine like terms: -20x + 20x = 0
-42 + 20x + xF + -2x2 = 0 + 2x2 + -2x2
-42 + 20x + xF + -2x2 = 2x2 + -2x2

Combine like terms: 2x2 + -2x2 = 0
-42 + 20x + xF + -2x2 = 0
