Quadratic Polynomial :
A polynomial of the second degree is called a quadratic polynomial. The general form of a quadratic polynomial is ax^2+bx+c; where a,b and c are real numbers, a not equal to 0 and x is a variable.
Example :
x^2 – 6x +4
Quadratic Equation:
An equation p(x) = 0, where p(x) is a quadratic polynomial, is called a quadratic equation. The general form of a quadratic equation is ax^2+bx+c where a, b and c are real numbers, a not equal to 0 and x is a variable.
Example:
x^2-2x+2 = 0
