This is parabolic quadratic equation because it is written in the form

**ax**

^{2}+ bx + c = 0This equation has 2 solutions because this equation has a degree of 2.

Also, if we use the quadratic formula to solve for x,

**x = (-b**

**± √(b**

^{2}- 4ac)) / 2awe will have two solutions. This is because of the plus/minus sign in the formula.

To determine whether they are real or imaginary, we examine the square-root part in the quadratic formula (aka the discriminant).

b

^{2}- 4ac ≥ 0 ----> real solutionb

^{2}- 4ac < 0 ----> imaginary solution
