x2 + 18x - 50 does not have rational factors.
That doesn't factor neatly. Applying the quadratic formula, we find two imaginary solutions: (-1 plus or minus one third itimes the square root of 7) divided by 4.x = -0.25 + 0.22047927592204922ix = -0.25 - 0.22047927592204922iwhere i is the square root of negative one.
