## FAQs on RD Sharma Solutions for Class 10 Maths Chapter 8 - Quadratic Equations

**1. What are the best books suggested for understanding Quadratic Equations?**

R. D. Sharma Class 10 Maths is the highlighted book recommended by teachers for proper understanding of the concepts with excellent use of examples and easy to tough questions after the completion of the chapter. The exercises ranging from 1 to 13, in chapter 8 of the book, have a variety of questions that students can solve for revision ahead of the exa. NCERT is also a highly suggested book if students are looking to get good marks in the Board exams.

**2. Are sample papers enough to solve Quadratic Equations?**

Maths means practice and only regular practice can help a student shine in the much reputed Board exams. Vedantu believes in bringing out the best of the students through its well-curated and aptly analyzed sample/mock papers, by experts, which can be downloaded in the PDF format for free. Most of the sample papers include questions similar to those in Previous Years’ Question papers along with a variety of other questions of a particular topic which will help clear all doubts.

**3. How do we remember the formulae of Quadratic Equations?**

Since the quadratic formula is a very long and cumbersome formula to remember, it is mandatory for the students to learn the formula since it is helpful to solve the questions. First is to understand the derivation of the formula and why it is used. Solve for two values- positive and negative. One of the best ways is to use mnemonics which aids memorisation. Many students also used images and actions to associate with the variables, symbols and numbers in the formula- this works well for visual learners.

**4. How to know the difference between a standard and a non-quadratic equation?**

While not all quadratic equations are in the standard form, one has to keep in mind that **a** should not be zero. Examples of standard quadratic equations are 6x^{2}+11x+5=0, x^{2}-x-3=0. Understanding quadratic equations is a foundational skill for both algebra and geometry. Now, if a student harnesses his/her algebra skills through practice, they can easily identify the loopholes. Some of the tricks to identify non-linear quadratic equations are:

Missing the Linear Coefficient: 2x

^{2}-64=0Missing the Constant Term: x

^{2}-8x=0

**5. How many questions are given related to Quadratic Equations in the Class 10 Board exams?**

Maths revolves mostly around various formulae. Students have to sharpen their algebra skills through rigorous practice since there is a tendency to forget the important formulae before the exam. According to the latest CBSE marking scheme, there are a total of 40 questions divided into four sections. There are five questions from Quadratic Equations and if a student has mastered the chapter, then the questions will be very easy and extremely scoring. The questions are either in the form of a Multiple Choice Question (MCQ) or as a Short/Long type question.
