(d*d)+(12*12)=484

Solution for (d*d)+(12*12)=484 equation:

Simplifying
(d * d) + (12 * 12) = 484

Multiply d * d
(d2) + (12 * 12) = 484
d2 + (12 * 12) = 484

Multiply 12 * 12
d2 + (144) = 484
d2 + 144 = 484

Reorder the terms:
144 + d2 = 484

Solving
144 + d2 = 484

Solving for variable 'd'.

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

Add '-144' to each side of the equation.
144 + -144 + d2 = 484 + -144

Combine like terms: 144 + -144 = 0
0 + d2 = 484 + -144
d2 = 484 + -144

Combine like terms: 484 + -144 = 340
d2 = 340

Simplifying
d2 = 340

Take the square root of each side:
d = {-18.439088915, 18.439088915}
