Solution for (h-2)(h-6)=3 equation:


Simplifying
(h + -2)(h + -6) = 3

Reorder the terms:
(-2 + h)(h + -6) = 3

Reorder the terms:
(-2 + h)(-6 + h) = 3

Multiply (-2 + h) * (-6 + h)
(-2(-6 + h) + h(-6 + h)) = 3
((-6 * -2 + h * -2) + h(-6 + h)) = 3
((12 + -2h) + h(-6 + h)) = 3
(12 + -2h + (-6 * h + h * h)) = 3
(12 + -2h + (-6h + h2)) = 3

Combine like terms: -2h + -6h = -8h
(12 + -8h + h2) = 3

Solving
12 + -8h + h2 = 3

Solving for variable 'h'.

Reorder the terms:
12 + -3 + -8h + h2 = 3 + -3

Combine like terms: 12 + -3 = 9
9 + -8h + h2 = 3 + -3

Combine like terms: 3 + -3 = 0
9 + -8h + h2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-9' to each side of the equation.
9 + -8h + -9 + h2 = 0 + -9

Reorder the terms:
9 + -9 + -8h + h2 = 0 + -9

Combine like terms: 9 + -9 = 0
0 + -8h + h2 = 0 + -9
-8h + h2 = 0 + -9

Combine like terms: 0 + -9 = -9
-8h + h2 = -9

The h term is -8h.  Take half its coefficient (-4).
Square it (16) and add it to both sides.

Add '16' to each side of the equation.
-8h + 16 + h2 = -9 + 16

Reorder the terms:
16 + -8h + h2 = -9 + 16

Combine like terms: -9 + 16 = 7
16 + -8h + h2 = 7
