Log On
Completing the square is inconvenient because the coefficient on the x term is odd, so just use the quadratic formula:
37 is prime so there is no further simplification possible, and the two values presented above are the exact roots of the equation. As to the 3-decimal place accurate approximation, you can push calculator buttons as well as I can.
