When b 2 4 a c 0 there is one real root. Only if it can be put in the form ax 2 bx c 0 and a is not zero. A polynomial of degree two is called a quadratic polynomial.
If 3 and -3 are the solutions of equation ax2 bx - 9 0.
Where a b c are real numbers and the important thing is a must be not equal to zero. The solution is A. A quadratic equation is a polynomial of second degree usually in the form of f x ax 2 bx c where a b c R and a 0. We can help you solve an equation of the form ax 2 bx c 0 Just enter the values of a b and c below.
