How do you factor x2 plus 3x plus 9?
x2 + 3x + 9 has no real solutions. Applying the quadratic formula, we get two imaginary solutions: (negative three plus or minus three i times the square root of three) divided by two.x = -1.5 + 2.598076211353316ix = -1.5 - 2.598076211353316iwhere i is the square root of negative one.

What is the square root of a negative number plus the square root of a negative number?
Nothing. You cannot have a square root of a negative number. The square root of negative one is called i, but i is an imaginary number. It does not exist and does not follow the properties of real numbers. (For example, if a and b are positive, then the square root of a times the square root of b is the square root of ab. But the square root of -7 is not the square root of 7 times i.)
