((2.7)(2.7))+((a)(a))=((3)(3))

Solution for ((2.7)(2.7))+((a)(a))=((3)(3)) equation:

Simplifying
((2.7)(2.7)) + ((a)(a)) = ((3)(3))

Multiply 2.7 * 2.7
(7.29) + ((a)(a)) = ((3)(3))
7.29 + ((a)(a)) = ((3)(3))

Multiply a * a
7.29 + (a2) = ((3)(3))
7.29 + a2 = ((3)(3))

Multiply 3 * 3
7.29 + a2 = (9)
7.29 + a2 = 9

Solving
7.29 + a2 = 9

Solving for variable 'a'.

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

Add '-7.29' to each side of the equation.
7.29 + -7.29 + a2 = 9 + -7.29

Combine like terms: 7.29 + -7.29 = 0.00
0.00 + a2 = 9 + -7.29
a2 = 9 + -7.29

Combine like terms: 9 + -7.29 = 1.71
a2 = 1.71

Simplifying
a2 = 1.71

Take the square root of each side:
a = {-1.307669683, 1.307669683}
