Answer: No solution
Explanation:
Set both equation equal to each other
x+3 = 2x^2-x-1
2x^2+2 = 0
What ever x is either positive or negative the result of the function will always be positive. Since we have a +2 at the end.
We can try to solve the eqution to prove
2x^2+2 = 0
x^2 = -1
And x^2 could never be negative
