((a)(a))+((6)(6))=((11.2)(11.2))

Solution for ((a)(a))+((6)(6))=((11.2)(11.2)) equation:

Simplifying
((a)(a)) + ((6)(6)) = ((11.2)(11.2))

Multiply a * a
(a2) + ((6)(6)) = ((11.2)(11.2))
a2 + ((6)(6)) = ((11.2)(11.2))

Multiply 6 * 6
a2 + (36) = ((11.2)(11.2))
a2 + 36 = ((11.2)(11.2))

Reorder the terms:
36 + a2 = ((11.2)(11.2))

Multiply 11.2 * 11.2
36 + a2 = (125.44)
36 + a2 = 125.44

Solving
36 + a2 = 125.44

Solving for variable 'a'.

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

Add '-36' to each side of the equation.
36 + -36 + a2 = 125.44 + -36

Combine like terms: 36 + -36 = 0
0 + a2 = 125.44 + -36
a2 = 125.44 + -36

Combine like terms: 125.44 + -36 = 89.44
a2 = 89.44

Simplifying
a2 = 89.44

Take the square root of each side:
a = {-9.457272334, 9.457272334}
