let x = length of shorter leg
then longer leg = x+___
and hypotenuse = x+___
Now substitute these expressions into the formula " square of hypotenuse equals sum of squares of the legs"
You will be squaring binomials; (x+3)2 will be x2 + 6x + 9, of course.
you will ultimately have a quadratic equation which you are expected to be able to solve, either by factoring or by use of the quadratic formula.
