Answer:

(A, B, C) = (2, 5, 2)

Explanation:

Undo the square operation by taking the square root. Both the positive and negative square roots are solutions to the equation.

`c -2 = \pm√(50)`

Add 2 to both sides of the equation:

`c = 2\pm√(50)`

Simplify the square root:

`c=2\pm√(25\cdot2)=2\pm√(25)\cdot√(2)\\\\\boxed{c=2\pm5√(2)}\qquad\text{A=2, B=5, C=2}`

Square roots are simplified by factoring out the factors that are perfect squares.
