We are doing this right now in math. It's a subtraction problem and its really simple. But before you do the problem, any signs on the bottom have to be reversed, so if its a positive, you have to change it to a negative, so now you're adding. So -5x^2 plus -6x^2 is -11x^2. then you have to add -5x and x, which would be -4x. leave the three alone, and it should come out as this:

-11x^2-4x+3
Distribute the negative so you get
-5x^2-5x+3-6x^2+x
Combine like terms
-11x^2-4x+3
That is the simplified answer, I dont know how far in algebra you are so I dont know what you really need....
-5x^2-5x+3-6x^2+x
-11x^2-4x+3
Can we use the quadratic formula?
Check: b^2-4ac is not negative?
(-4)^2-4(-11)(3)=16+132=148=not negative
Use the quadratic formula.
I tried to do this problem and i got to
-11x^2-4x+3=0
and that is as far as you can simplify it which means you can solve it so the answer is "No Solution"
