Chapter 4 Exercise 4D Q.N 15 and 19 (iii) || Class 10 Maths R S Aggarwal || Quadratic Equations
‪@RajeshTutorials‬
Dear students .......
Quadratic Equations is a very interesting chapter in Class 10 Mathematics. In this chapter, we have to study how to solve quadratic equations - by factorisation method, by quadratic formula method, Nature of roots - real and distinct, real and equal and imaginary roots and word problems.

📝📝About the video :
In this video - I have discussed questions based on nature of roots. First question is based on real and equal roots and second question on real and distinct roots

✅About the video :
👉👉Class 10 Mathematics CBSE
👉👉Chapter 4 Quadratic Equations
👉👉Book used - R S Aggarwal New Edition Book
👉👉Topic - Nature of roots
👉👉Sub topic - real and equal roots, real and distinct roots
👉👉Number of Questions - 2


👉Q - If the roots of the equation (c²-ab)x²-2(a²-bc)x+b²-ac = 0
are real and equal,show that either a=0 or a³+b³+c³= 3abc.

👉Q- Find the value of k for which 9x²+3kx+4 = 0
has real and distinct roots.

✅These questions are very difficult for students. I have pointed #1 at 10:57 .

#1 This is the point where students do mistakes. I have explained how can they save themselves by doing mistakes at 13:00-17:11

This video is helpful for those students who are going to appear in Board Exams of CBSE , ICSE , State Boards and competitions like SSC, RAILWAYS, BANKING, CTET etc.
