For this, you are looking for the Quadratic Formula or Completing The Square. This is because we are unable to factorise the given equation above. Lets use the former way mentioned because it is really just using a set formula and replacing the letters with numbers (less chance of human error).
Here is the quadratic formula:
So now we take the letters A, B and C and give them the values 2, 6 and 11 respectively.
One quick thing to note is what a rational number is; A rational number is a number that can be written as a simple fraction.
Now just replace those numbers into the formula and we get:
With:
A = -1.5
B = 0.25
C = -52
