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

Add '-9' to each side of the equation.
9 + -9 + a2 = 49 + -9

Combine like terms: 9 + -9 = 0
0 + a2 = 49 + -9
a2 = 49 + -9

Combine like terms: 49 + -9 = 40
a2 = 40

Simplifying
a2 = 40

Take the square root of each side:
a = {-6.32455532, 6.32455532}
