NCERT Solutions Class 10 Maths Chapter 4 Quadratic Equations contain all the solutions to the problems provided in the Class 10 Maths NCERT textbook for CBSE exam preparations. The questions from every section are framed and solved accurately by the subject experts.
A quadratic equation in the variable x is an equation of the form ax 2 + bx + c = 0, where a, b, c are real numbers, a ? 0. That is, ax 2 + bx + c = 0, a ? 0 is called the standard form of a quadratic equation. Quadratic equations arise in several situations around us.
A quadratic equation in the variable x is an equation of the form ax 2 + bx + c = 0, where a, b, c are real numbers, a ? 0. In fact, any equation of the form p (x) = 0, where p (x) is a polynomial of degree 2, is a quadratic equation.
In general, a real number ? is called a root of the quadratic equation ax2+ bx+ c= 0, a? 0 if a?2+ b? + c= 0. We also say that x=???is a solution of the quadratic equation, or that ???satisfies the quadratic equation.
