Solution for V(x)=(70-2x)(50-2x) equation: 


Simplifying
V(x) = (70 + -2x)(50 + -2x)

Multiply V * x
xV = (70 + -2x)(50 + -2x)

Multiply (70 + -2x) * (50 + -2x)
xV = (70(50 + -2x) + -2x * (50 + -2x))
xV = ((50 * 70 + -2x * 70) + -2x * (50 + -2x))
xV = ((3500 + -140x) + -2x * (50 + -2x))
xV = (3500 + -140x + (50 * -2x + -2x * -2x))
xV = (3500 + -140x + (-100x + 4x2))

Combine like terms: -140x + -100x = -240x
xV = (3500 + -240x + 4x2)

Solving
xV = 3500 + -240x + 4x2

Solving for variable 'x'.

Reorder the terms:
-3500 + 240x + xV + -4x2 = 3500 + -240x + 4x2 + -3500 + 240x + -4x2

Reorder the terms:
-3500 + 240x + xV + -4x2 = 3500 + -3500 + -240x + 240x + 4x2 + -4x2

Combine like terms: 3500 + -3500 = 0
-3500 + 240x + xV + -4x2 = 0 + -240x + 240x + 4x2 + -4x2
-3500 + 240x + xV + -4x2 = -240x + 240x + 4x2 + -4x2

Combine like terms: -240x + 240x = 0
-3500 + 240x + xV + -4x2 = 0 + 4x2 + -4x2
-3500 + 240x + xV + -4x2 = 4x2 + -4x2

Combine like terms: 4x2 + -4x2 = 0
-3500 + 240x + xV + -4x2 = 0
