((15)(15))+((b)(b))=((30)(30))

Solution for ((15)(15))+((b)(b))=((30)(30)) equation:

Simplifying
((15)(15)) + ((b)(b)) = ((30)(30))

Multiply 15 * 15
(225) + ((b)(b)) = ((30)(30))
225 + ((b)(b)) = ((30)(30))

Multiply b * b
225 + (b2) = ((30)(30))
225 + b2 = ((30)(30))

Multiply 30 * 30
225 + b2 = (900)
225 + b2 = 900

Solving
225 + b2 = 900

Solving for variable 'b'.

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

Add '-225' to each side of the equation.
225 + -225 + b2 = 900 + -225

Combine like terms: 225 + -225 = 0
0 + b2 = 900 + -225
b2 = 900 + -225

Combine like terms: 900 + -225 = 675
b2 = 675

Simplifying
b2 = 675

Take the square root of each side:
b = {-25.980762114, 25.980762114}
