"The length of the hypotenuse of a right triangle is 4 cm more than the longer leg. The length of the longer leg is 14 cm more than the length of the shorter leg. Find the number of centimeters in the length of each side of the right triangle."

I know the answers are 16, 30, 34, but I have to show my work, and when I use the "a^2 + b^2 = c^2" formula, I always get the answer "sqrt[128]". What am I doing wrong?

This is what I do:

. . .x^2 + (x + 14)^2 = (x + 18)^2

. . .2x^2 + 196 = x^2 + 324

. . .x^2 = 128

. . .x = ????
