These quadratic equations notes help the students to recall the important definitions, formulas and tricks to solve the problems in the CBSE Board Exams 2021-22. In this article, you will learn the concept of quadratic equations, standard form, nature of roots, methods for finding the solution for the given quadratic equations with more examples.

Write the quadratic function in standard form given the roots: -2 and 3 Section 3 VERTEX Form: y = (x - h)2+ k, where h is the x-value of the vertex and k is the y-value of the vertex.

Steps to solve quadratic equations by factoring: 1. Write the equation in standard form (equal to 0). 2. Factor the polynomial. 3. Use the Zero Product Property to set each factor equal to zero. 4. Solve each resulting linear equation.

In the method of completing the squares, the quadratic equation is expressed in the form (x±k)2=p2. (i) Express the quadratic equation in standard form.
