Hello Red Ruby!

In this case, you can solve this as a system of equations. You can assume that y = y to compare both equations as below:

$$y = y \Rightarrow 2x - 1 = (x+6)^2 + 11$$

You can then isolate all the equations on one side to have an equation following the format $$0 = ax^2 + bx + c$$. You can then find the value for $$b^2 - 4ac$$ to determine of the system will admit one, two or no solutions.
