Solution for R(x)=x(85-2x) equation:


Simplifying
R(x) = x(85 + -2x)

Multiply R * x
xR = x(85 + -2x)
xR = (85 * x + -2x * x)
xR = (85x + -2x2)

Solving
xR = 85x + -2x2

Solving for variable 'x'.

Reorder the terms:
-85x + xR + 2x2 = 85x + -2x2 + -85x + 2x2

Reorder the terms:
-85x + xR + 2x2 = 85x + -85x + -2x2 + 2x2

Combine like terms: 85x + -85x = 0
-85x + xR + 2x2 = 0 + -2x2 + 2x2
-85x + xR + 2x2 = -2x2 + 2x2

x(-85 + R + 2x) = 0

Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(-85 + R + 2x)' equal to zero and attempt to solve: Simplifying -85 + R + 2x = 0 Solving -85 + R + 2x = 0 Move all terms containing x to the left, all other terms to the right. Add '85' to each side of the equation. -85 + R + 85 + 2x = 0 + 85 Reorder the terms: -85 + 85 + R + 2x = 0 + 85 Combine like terms: -85 + 85 = 0 0 + R + 2x = 0 + 85 R + 2x = 0 + 85 Combine like terms: 0 + 85 = 85 R + 2x = 85 Add '-1R' to each side of the equation. R + -1R + 2x = 85 + -1R Combine like terms: R + -1R = 0 0 + 2x = 85 + -1R 2x = 85 + -1R Divide each side by '2'. x = 42.5 + -0.5R Simplifying x = 42.5 + -0.5R

Solution

x = {0, 42.5 + -0.5R}
