QUADRATIC EQUATION
A polynomial of degree two is called quadratic polynomial
General form of quadratic polynomial is ax2+bx+c, a,b,c are real numbers and a≠0.
If for x= α, α ϵ R, the value of quadratic polynomial becomes zero, then α is called zero of the quadratic polynomial.
The equation ax2+bx+c=0, a≠0 is called quadratic equation.
If α and β are two zeros of ax2+bx+c=0, then we say that α and β are roots of the quadratic equation.
