Solution for 0=(10-.05X)(60+X) equation:


Simplifying
0 = (10 + -0.05X)(60 + X)

Multiply (10 + -0.05X) * (60 + X)
0 = (10(60 + X) + -0.05X * (60 + X))
0 = ((60 * 10 + X * 10) + -0.05X * (60 + X))
0 = ((600 + 10X) + -0.05X * (60 + X))
0 = (600 + 10X + (60 * -0.05X + X * -0.05X))
0 = (600 + 10X + (-3X + -0.05X2))

Combine like terms: 10X + -3X = 7X
0 = (600 + 7X + -0.05X2)

Solving
0 = 600 + 7X + -0.05X2

Solving for variable 'X'.

Combine like terms: 0 + -600 = -600
-600 + -7X + 0.05X2 = 600 + 7X + -0.05X2 + -600 + -7X + 0.05X2

Reorder the terms:
-600 + -7X + 0.05X2 = 600 + -600 + 7X + -7X + -0.05X2 + 0.05X2

Combine like terms: 600 + -600 = 0
-600 + -7X + 0.05X2 = 0 + 7X + -7X + -0.05X2 + 0.05X2
-600 + -7X + 0.05X2 = 7X + -7X + -0.05X2 + 0.05X2

Combine like terms: 7X + -7X = 0
-600 + -7X + 0.05X2 = 0 + -0.05X2 + 0.05X2
-600 + -7X + 0.05X2 = -0.05X2 + 0.05X2

Combine like terms: -0.05X2 + 0.05X2 = 0.00
-600 + -7X + 0.05X2 = 0.00

Begin completing the square.  Divide all terms by
0.05 the coefficient of the squared term: 

Divide each side by '0.05'.
-12000 + -140X + X2 = 0

Move the constant term to the right:

Add '12000' to each side of the equation.
-12000 + -140X + 12000 + X2 = 0 + 12000

Reorder the terms:
-12000 + 12000 + -140X + X2 = 0 + 12000

Combine like terms: -12000 + 12000 = 0
0 + -140X + X2 = 0 + 12000
-140X + X2 = 0 + 12000

Combine like terms: 0 + 12000 = 12000
-140X + X2 = 12000

The X term is -140X.  Take half its coefficient (-70).
Square it (4900) and add it to both sides.

Add '4900' to each side of the equation.
-140X + 4900 + X2 = 12000 + 4900

Reorder the terms:
4900 + -140X + X2 = 12000 + 4900

Combine like terms: 12000 + 4900 = 16900
4900 + -140X + X2 = 16900

Factor a perfect square on the left side:
(X + -70)(X + -70) = 16900

Calculate the square root of the right side: 130

Break this problem into two subproblems by setting 
(X + -70) equal to 130 and -130.

Subproblem 1

X + -70 = 130 Simplifying X + -70 = 130 Reorder the terms: -70 + X = 130 Solving -70 + X = 130 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '70' to each side of the equation. -70 + 70 + X = 130 + 70 Combine like terms: -70 + 70 = 0 0 + X = 130 + 70 X = 130 + 70 Combine like terms: 130 + 70 = 200 X = 200 Simplifying X = 200

Subproblem 2

X + -70 = -130 Simplifying X + -70 = -130 Reorder the terms: -70 + X = -130 Solving -70 + X = -130 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '70' to each side of the equation. -70 + 70 + X = -130 + 70 Combine like terms: -70 + 70 = 0 0 + X = -130 + 70 X = -130 + 70 Combine like terms: -130 + 70 = -60 X = -60 Simplifying X = -60

Solution

The solution to the problem is based on the solutions from the subproblems. X = {200, -60}
