Class 12 Basic Mathematics Quadratic Equations Solution and Guide

Quadratic equations are a fundamental topic in mathematics and play a vital role in Class 12 Basic Mathematics. Understanding quadratic equations not only prepares students for NEB examinations but also builds a foundation for solving real-world problems in various fields. To support students in mastering this topic, we have created a detailed Quadratic Equations Solution and Guide.

This guide is based on the Class 12 Basic Mathematics textbook approved by the Curriculum Development Center of Nepal. It covers all essential aspects of quadratic equations, including their definition, solution methods, and applications, ensuring students are fully prepared for exams and assignments.

A quadratic equation is a second-degree polynomial represented as $a{x}^2+bx+c=0$, where $a,b,$ and $c$ are constants, and $a\mathrm{\ne }0$. This guide explores multiple methods to solve quadratic equations, such as factoring, completing the square, and using the quadratic formula $x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$. It also delves into the graphical interpretation of quadratic functions, which helps visualize their roots.

The discriminant, $\mathrm{\Delta }=b^2-4ac$, plays a crucial role in determining the nature of the roots of a quadratic equation. Students will learn to analyze how $\mathrm{\Delta }>0$, $\mathrm{\Delta }=0$, and $\mathrm{\Delta }<0$ correspond to distinct real roots, repeated real roots, and complex roots, respectively. This knowledge is reinforced with solved examples and practice problems tailored to NEB examination standards.

In addition to theoretical concepts, the guide highlights practical applications of quadratic equations in real-life scenarios, such as solving problems related to projectile motion, profit maximization, and area calculations. These examples demonstrate how quadratic equations are not just abstract mathematical expressions but tools with significant practical value.
