Solution for h(h+6)=33.25 equation:


Simplifying
h(h + 6) = 33.25

Reorder the terms:
h(6 + h) = 33.25
(6 * h + h * h) = 33.25
(6h + h2) = 33.25

Solving
6h + h2 = 33.25

Solving for variable 'h'.

Reorder the terms:
-33.25 + 6h + h2 = 33.25 + -33.25

Combine like terms: 33.25 + -33.25 = 0.00
-33.25 + 6h + h2 = 0.00

Begin completing the square.

Move the constant term to the right:

Add '33.25' to each side of the equation.
-33.25 + 6h + 33.25 + h2 = 0.00 + 33.25

Reorder the terms:
-33.25 + 33.25 + 6h + h2 = 0.00 + 33.25

Combine like terms: -33.25 + 33.25 = 0.00
0.00 + 6h + h2 = 0.00 + 33.25
6h + h2 = 0.00 + 33.25

Combine like terms: 0.00 + 33.25 = 33.25
6h + h2 = 33.25

The h term is 6h.  Take half its coefficient (3).
Square it (9) and add it to both sides.

Add '9' to each side of the equation.
6h + 9 + h2 = 33.25 + 9

Reorder the terms:
9 + 6h + h2 = 33.25 + 9

Combine like terms: 33.25 + 9 = 42.25
9 + 6h + h2 = 42.25

Factor a perfect square on the left side:
(h + 3)(h + 3) = 42.25

Calculate the square root of the right side: 6.5

Break this problem into two subproblems by setting 
(h + 3) equal to 6.5 and -6.5.

Subproblem 1

h + 3 = 6.5 Simplifying h + 3 = 6.5 Reorder the terms: 3 + h = 6.5 Solving 3 + h = 6.5 Solving for variable 'h'. Move all terms containing h to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + h = 6.5 + -3 Combine like terms: 3 + -3 = 0 0 + h = 6.5 + -3 h = 6.5 + -3 Combine like terms: 6.5 + -3 = 3.5 h = 3.5 Simplifying h = 3.5

Subproblem 2

h + 3 = -6.5 Simplifying h + 3 = -6.5 Reorder the terms: 3 + h = -6.5 Solving 3 + h = -6.5 Solving for variable 'h'. Move all terms containing h to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + h = -6.5 + -3 Combine like terms: 3 + -3 = 0 0 + h = -6.5 + -3 h = -6.5 + -3 Combine like terms: -6.5 + -3 = -9.5 h = -9.5 Simplifying h = -9.5

Solution

The solution to the problem is based on the solutions from the subproblems. h = {3.5, -9.5}
