Solution for (x+3.5)(x-3.52)=0 equation:


Simplifying
(x + 3.5)(x + -3.52) = 0

Reorder the terms:
(3.5 + x)(x + -3.52) = 0

Reorder the terms:
(3.5 + x)(-3.52 + x) = 0

Multiply (3.5 + x) * (-3.52 + x)
(3.5(-3.52 + x) + x(-3.52 + x)) = 0
((-3.52 * 3.5 + x * 3.5) + x(-3.52 + x)) = 0
((-12.32 + 3.5x) + x(-3.52 + x)) = 0
(-12.32 + 3.5x + (-3.52 * x + x * x)) = 0
(-12.32 + 3.5x + (-3.52x + x2)) = 0

Combine like terms: 3.5x + -3.52x = -0.02x
(-12.32 + -0.02x + x2) = 0

Solving
-12.32 + -0.02x + x2 = 0

Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '12.32' to each side of the equation.
-12.32 + -0.02x + 12.32 + x2 = 0 + 12.32

Reorder the terms:
-12.32 + 12.32 + -0.02x + x2 = 0 + 12.32

Combine like terms: -12.32 + 12.32 = 0.00
0.00 + -0.02x + x2 = 0 + 12.32
-0.02x + x2 = 0 + 12.32

Combine like terms: 0 + 12.32 = 12.32
-0.02x + x2 = 12.32

The x term is -0.02x.  Take half its coefficient (-0.01).
Square it (0.0001) and add it to both sides.

Add '0.0001' to each side of the equation.
-0.02x + 0.0001 + x2 = 12.32 + 0.0001

Reorder the terms:
0.0001 + -0.02x + x2 = 12.32 + 0.0001

Combine like terms: 12.32 + 0.0001 = 12.3201
0.0001 + -0.02x + x2 = 12.3201

Factor a perfect square on the left side:
(x + -0.01)(x + -0.01) = 12.3201

Calculate the square root of the right side: 3.51

Break this problem into two subproblems by setting 
(x + -0.01) equal to 3.51 and -3.51.

Subproblem 1

x + -0.01 = 3.51 Simplifying x + -0.01 = 3.51 Reorder the terms: -0.01 + x = 3.51 Solving -0.01 + x = 3.51 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.01' to each side of the equation. -0.01 + 0.01 + x = 3.51 + 0.01 Combine like terms: -0.01 + 0.01 = 0.00 0.00 + x = 3.51 + 0.01 x = 3.51 + 0.01 Combine like terms: 3.51 + 0.01 = 3.52 x = 3.52 Simplifying x = 3.52

Subproblem 2

x + -0.01 = -3.51 Simplifying x + -0.01 = -3.51 Reorder the terms: -0.01 + x = -3.51 Solving -0.01 + x = -3.51 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.01' to each side of the equation. -0.01 + 0.01 + x = -3.51 + 0.01 Combine like terms: -0.01 + 0.01 = 0.00 0.00 + x = -3.51 + 0.01 x = -3.51 + 0.01 Combine like terms: -3.51 + 0.01 = -3.5 x = -3.5 Simplifying x = -3.5

Solution

The solution to the problem is based on the solutions from the subproblems. x = {3.52, -3.5}
