Find the lengths of the sides of a right triangle if the hypotenuse is 9 centimeters longer than the shorter leg
and 2 centimeters longer than the longer leg
~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The Pythagorean equation is 

%28x-9%29%5E2+%2B+%28x-2%29%5E2 = x%5E2.

Solve it and get the answer.

x%5E2+-+18x+%2B+81+%2B+x%5E2+-+4x+%2B+4 = x%5E2,

x%5E2+-+22x+%2B+85 = 0,

(x-17)*(x-5) = 0,

x = 17  is the only root satisfying the condition.

Answer. Hypotenuse is 17 cm, the legs are 8 cm and 15 cm.
