(h+5)(h-5)=

Solution for (h+5)(h-5)= equation:

Simplifying
(h + 5)(h + -5) = 0

Reorder the terms:
(5 + h)(h + -5) = 0

Reorder the terms:
(5 + h)(-5 + h) = 0

Multiply (5 + h) * (-5 + h)
(5(-5 + h) + h(-5 + h)) = 0
((-5 * 5 + h * 5) + h(-5 + h)) = 0
((-25 + 5h) + h(-5 + h)) = 0
(-25 + 5h + (-5 * h + h * h)) = 0
(-25 + 5h + (-5h + h2)) = 0

Combine like terms: 5h + -5h = 0
(-25 + 0 + h2) = 0
(-25 + h2) = 0

Solving
-25 + h2 = 0

Solving for variable 'h'.

Move all terms containing h to the left, all other terms to the right.

Add '25' to each side of the equation.
-25 + 25 + h2 = 0 + 25

Combine like terms: -25 + 25 = 0
0 + h2 = 0 + 25
h2 = 0 + 25

Combine like terms: 0 + 25 = 25
h2 = 25

Simplifying
h2 = 25

Take the square root of each side:
h = {-5, 5}
