Solution for (14.5-x)(-7-x)=0 equation:


Simplifying
(14.5 + -1x)(-7 + -1x) = 0

Multiply (14.5 + -1x) * (-7 + -1x)
(14.5(-7 + -1x) + -1x * (-7 + -1x)) = 0
((-7 * 14.5 + -1x * 14.5) + -1x * (-7 + -1x)) = 0
((-101.5 + -14.5x) + -1x * (-7 + -1x)) = 0
(-101.5 + -14.5x + (-7 * -1x + -1x * -1x)) = 0
(-101.5 + -14.5x + (7x + 1x2)) = 0

Combine like terms: -14.5x + 7x = -7.5x
(-101.5 + -7.5x + 1x2) = 0

Solving
-101.5 + -7.5x + 1x2 = 0

Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '101.5' to each side of the equation.
-101.5 + -7.5x + 101.5 + x2 = 0 + 101.5

Reorder the terms:
-101.5 + 101.5 + -7.5x + x2 = 0 + 101.5

Combine like terms: -101.5 + 101.5 = 0.0
0.0 + -7.5x + x2 = 0 + 101.5
-7.5x + x2 = 0 + 101.5

Combine like terms: 0 + 101.5 = 101.5
-7.5x + x2 = 101.5

The x term is -7.5x.  Take half its coefficient (-3.75).
Square it (14.0625) and add it to both sides.

Add '14.0625' to each side of the equation.
-7.5x + 14.0625 + x2 = 101.5 + 14.0625

Reorder the terms:
14.0625 + -7.5x + x2 = 101.5 + 14.0625

Combine like terms: 101.5 + 14.0625 = 115.5625
14.0625 + -7.5x + x2 = 115.5625

Factor a perfect square on the left side:
(x + -3.75)(x + -3.75) = 115.5625

Calculate the square root of the right side: 10.75

Break this problem into two subproblems by setting 
(x + -3.75) equal to 10.75 and -10.75.

Subproblem 1

x + -3.75 = 10.75 Simplifying x + -3.75 = 10.75 Reorder the terms: -3.75 + x = 10.75 Solving -3.75 + x = 10.75 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.75' to each side of the equation. -3.75 + 3.75 + x = 10.75 + 3.75 Combine like terms: -3.75 + 3.75 = 0.00 0.00 + x = 10.75 + 3.75 x = 10.75 + 3.75 Combine like terms: 10.75 + 3.75 = 14.5 x = 14.5 Simplifying x = 14.5

Subproblem 2

x + -3.75 = -10.75 Simplifying x + -3.75 = -10.75 Reorder the terms: -3.75 + x = -10.75 Solving -3.75 + x = -10.75 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.75' to each side of the equation. -3.75 + 3.75 + x = -10.75 + 3.75 Combine like terms: -3.75 + 3.75 = 0.00 0.00 + x = -10.75 + 3.75 x = -10.75 + 3.75 Combine like terms: -10.75 + 3.75 = -7 x = -7 Simplifying x = -7

Solution
