Question 22863
I'm going to assume you want to solve these equations separately;
i.e. you do not want to solve them as a system of two quadratic 
equation.
If so you use the quadratic formula to solve the 2nd one as follows:
*[invoke quadratic "x",1,-5,6}
Then use the quadratic formula to solve the 1st one as follows;
*[invoke quadratic "x",1,1,-20]
