@@JakesMathLessons... Actually when we are interested in the imaginary numbers plane (ax + jb)(cx + jc) where j is defined as ✓(-1) if we aren't visualizing complex numbers on the polar number plane consisting of an imaginary axis j and a real axis x then the best solutions are from the quadratic equation ax^2 + bx + c factors into a (x/(2a) + 1/(2a) . ✓(b^2 - 4ac)) (x/(2a) - 1/(2a) . ✓(b^2 - 4ac)) so we don't say all the time there are no solutions to ax^2 + bx + c. There are factored solutions on a real axis and imaginary axis or plane defining those solutions. She then has to replace the words with "no solutions" to "no real axis solutions" of the plane actually factoring ax^2 + bx + c. Going further into calculus we consider factors as polar imaginary axis and real axis solutions of all polynomials (not just quadratic) making use of trigonometry describing the solutions.

Helpful tip: If you want to determine if the polynomial is factorable, find what the discrimnant is. The discrimant formula is:sqrt(b^2-4ac) and if the result of this comes out to be a perfect square, then it is factorable. If not, then it is prime (not factorable). (another helpful tip: polynomials are in the form : ax^2+bx+c)

You don't really need D to be a perfect square.
