((a)(a))+((10)(10))=((18)(18))

Solution for ((a)(a))+((10)(10))=((18)(18)) equation:

Simplifying
((a)(a)) + ((10)(10)) = ((18)(18))

Multiply a * a
(a2) + ((10)(10)) = ((18)(18))
a2 + ((10)(10)) = ((18)(18))

Multiply 10 * 10
a2 + (100) = ((18)(18))
a2 + 100 = ((18)(18))

Reorder the terms:
100 + a2 = ((18)(18))

Multiply 18 * 18
100 + a2 = (324)
100 + a2 = 324

Solving
100 + a2 = 324

Solving for variable 'a'.

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

Add '-100' to each side of the equation.
100 + -100 + a2 = 324 + -100

Combine like terms: 100 + -100 = 0
0 + a2 = 324 + -100
a2 = 324 + -100

Combine like terms: 324 + -100 = 224
a2 = 224

Simplifying
a2 = 224

Take the square root of each side:
a = {-14.966629547, 14.966629547}
