In algebra, a quadratic equation is any polynomial equation of the second degree with the following form: ax 2 + bx + c = 0. where x is an unknown, a is referred to as the quadratic coefficient, b the linear coefficient, and c the constant.
For the quadratic equation given by This discriminant tells us about the nature of the roots (values of x). If it is negative then you will be taking the square root of a negative number which is not a real number, In that case, the roots are imaginary (and there are 2 of them).

Find the roots of the quadratic equations by applying the quadratic formula. (i) 2x2 – 7x + 3 = 0 A quadratic equation is wholly defined by its coefficients. The solutions or roots of the quadratic can, therefore, be determined by a function of these coefficients - and this function called the quadratic If the discriminant of the quadratic equation is greater than zero then it will have 2 different roots.
