l^2+s^2=h^2
h=3*s-2
l=3*s-3
(3*s-3)^2+s^2=(3*s-2)^2
(3s-3)*(3s-3)=9s^2-6s+9
(3s-2)*(3s-2)=9s^2-4s+4
9s^2-6s+9+s^2=9s^2-4s+4
subtract 9s^2 from both sides
add 4s to both sides
subtract 4 from both sides
s^2-2s+5=0

Let's use the quadratic formula to solve for x:


Starting with the general quadratic





the general solution using the quadratic equation is:







So lets solve ( notice , , and )





Plug in a=1, b=-2, and c=5




Negate -2 to get 2




Square -2 to get 4 (note: remember when you square -2, you must square the negative as well. This is because .)




Multiply to get




Combine like terms in the radicand (everything under the square root)




Simplify the square root (note: If you need help with simplifying the square root, check out this solver)




Multiply 2 and 1 to get 2




After simplifying, the quadratic has roots of
