v(x)=(1.5)(5-2(1.5))(9-2(1.5))

Solution for v(x)=(1.5)(5-2(1.5))(9-2(1.5)) equation:

Simplifying
v(x) = (1.5)(5 + -2(1.5))(9 + -2(1.5))

Multiply v * x
vx = (1.5)(5 + -2(1.5))(9 + -2(1.5))

Multiply -2 * 1.5
vx = 1.5(5 + -3)(9 + -2(1.5))

Combine like terms: 5 + -3 = 2
vx = 1.5(2)(9 + -2(1.5))

Multiply -2 * 1.5
vx = 1.5 * 2(9 + -3)

Combine like terms: 9 + -3 = 6
vx = 1.5 * 2(6)

Multiply 1.5 * 2
vx = 3 * 6

Multiply 3 * 6
vx = 18

Solving
vx = 18

Solving for variable 'v'.

Move all terms containing v to the left, all other terms to the right.

Divide each side by 'x'.
v = 18x-1

Simplifying
v = 18x-1
