Polynomial equations are equations with forms such as y = ax^2 + bx + c or any other equation involving variables to some degree greater than 1. ... They take the form a + bi where a is the real part, and b is imaginary. ... Ultimately, what the quadratic formula (y = -b +/- the square root of b^2 -4ac divided by 2a) tells one is the roots of the equation. ... For example, when solving the following quadratic equation, y = x^2 + 4x + 29, using the quadratic formula where a = 1, b = 4, and c = 29, one, comes out with the solution, -2 + 5i. ...
