CBSE Class 10 - Maths - Quadratic Equations - Summary

Quadratic Equations - Summary

① A polynomial of degree 2 is called quadrilateral polynomial. The general form of a quadrilateral polynomial is ax² + bx+ c, where a, b, c are real numbers such that a ≠ 0 and x is a real variable.


② If p(x) = ax²  + bx + c, a ≠ 0 is a quadratic polynomial and α is a real number, then p(α) = aα² + bα + c is known as the value of the quadratic polynomial p(x).

③ A real number α is said to be a zero of the quadratic polynomial p(x) = ax²  + bx + c, if p(α) = 0.

④ If p(x) = ax²  + bx + c is a quadratic polynomial,then p(x) = 0 i.e. ax²  + bx + c = 0, a ≠ 0 is called a quadratic equation.

⑤ A real number α is said to be root of the quadratic equation ax²  + bx + c = 0, if aα² + bα + c = 0.
In other words, α is a root of ax²  + bx + c = 0 if and only if α is zero pf the polynomial p(x) = ax²  + bx + c.
