Solution for 2hsquared-20=(h+4)(h-4) equation:


Simplifying
2hsquared + -20 = (h + 4)(h + -4)

Reorder the terms:
-20 + 2adehqrsu = (h + 4)(h + -4)

Reorder the terms:
-20 + 2adehqrsu = (4 + h)(h + -4)

Reorder the terms:
-20 + 2adehqrsu = (4 + h)(-4 + h)

Multiply (4 + h) * (-4 + h)
-20 + 2adehqrsu = (4(-4 + h) + h(-4 + h))
-20 + 2adehqrsu = ((-4 * 4 + h * 4) + h(-4 + h))
-20 + 2adehqrsu = ((-16 + 4h) + h(-4 + h))
-20 + 2adehqrsu = (-16 + 4h + (-4 * h + h * h))
-20 + 2adehqrsu = (-16 + 4h + (-4h + h2))

Combine like terms: 4h + -4h = 0
-20 + 2adehqrsu = (-16 + 0 + h2)
-20 + 2adehqrsu = (-16 + h2)

Solving
-20 + 2adehqrsu = -16 + h2

Solving for variable 'a'.

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

Add '20' to each side of the equation.
-20 + 20 + 2adehqrsu = -16 + 20 + h2

Combine like terms: -20 + 20 = 0
0 + 2adehqrsu = -16 + 20 + h2
2adehqrsu = -16 + 20 + h2

Combine like terms: -16 + 20 = 4
2adehqrsu = 4 + h2

Divide each side by '2dehqrsu'.
a = 2d-1e-1h-1q-1r-1s-1u-1 + 0.5d-1e-1hq-1r-1s-1u-1

Simplifying
a = 2d-1e-1h-1q-1r-1s-1u-1 + 0.5d-1e-1hq-1r-1s-1u-1
