Solution for (n+3)(n-2)=88 equation:


Simplifying
(n + 3)(n + -2) = 88

Reorder the terms:
(3 + n)(n + -2) = 88

Reorder the terms:
(3 + n)(-2 + n) = 88

Multiply (3 + n) * (-2 + n)
(3(-2 + n) + n(-2 + n)) = 88
((-2 * 3 + n * 3) + n(-2 + n)) = 88
((-6 + 3n) + n(-2 + n)) = 88
(-6 + 3n + (-2 * n + n * n)) = 88
(-6 + 3n + (-2n + n2)) = 88

Combine like terms: 3n + -2n = 1n
(-6 + 1n + n2) = 88

Solving
-6 + 1n + n2 = 88

Solving for variable 'n'.

Reorder the terms:
-6 + -88 + 1n + n2 = 88 + -88

Combine like terms: -6 + -88 = -94
-94 + 1n + n2 = 88 + -88

Combine like terms: 88 + -88 = 0
-94 + 1n + n2 = 0

Begin completing the square.

Move the constant term to the right:

Add '94' to each side of the equation.
-94 + 1n + 94 + n2 = 0 + 94

Reorder the terms:
-94 + 94 + 1n + n2 = 0 + 94

Combine like terms: -94 + 94 = 0
0 + 1n + n2 = 0 + 94
1n + n2 = 0 + 94

Combine like terms: 0 + 94 = 94
1n + n2 = 94

The n term is 1n.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
n + 0.25 + n2 = 94 + 0.25

Reorder the terms:
0.25 + n + n2 = 94 + 0.25

Combine like terms: 94 + 0.25 = 94.25
0.25 + n + n2 = 94.25

Factor a perfect square on the left side:
(n + 0.5)(n + 0.5) = 94.25

Calculate the square root of the right side: 9.708243919

Break this problem into two subproblems by setting 
(n + 0.5) equal to 9.708243919 and -9.708243919.

Subproblem 1

n + 0.5 = 9.708243919 Simplifying n + 0.5 = 9.708243919 Reorder the terms: 0.5 + n = 9.708243919 Solving 0.5 + n = 9.708243919 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + n = 9.708243919 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + n = 9.708243919 + -0.5 n = 9.708243919 + -0.5 Combine like terms: 9.708243919 + -0.5 = 9.208243919 n = 9.208243919 Simplifying n = 9.208243919

Subproblem 2

n + 0.5 = -9.708243919 Simplifying n + 0.5 = -9.708243919 Reorder the terms: 0.5 + n = -9.708243919 Solving 0.5 + n = -9.708243919 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + n = -9.708243919 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + n = -9.708243919 + -0.5 n = -9.708243919 + -0.5 Combine like terms: -9.708243919 + -0.5 = -10.208243919 n = -10.208243919 Simplifying n = -10.208243919
