I dont know the answer

You know an equation is quadratic by looking at the degree of the highest power in the equation. If it is 2, then it is quadratic. so any equation or polynomial of the form: ax2 +bx+c=0 where a is NOT 0 and a, b and c are known as the quadratic coefficients is a quadratic equation.

Suppose the quadratic is a*x^2 + bx + c = 0If b^2 >= 4ac then the quadratic has real roots.If b^2 < 4ac then the quadratic has no real roots.
