Class 10 Exercise 5.4 Q1, Q2 & Q3 | Chapter 5 | Solve Equations by (Let y = x²) & Quadratic Formula

In this video, we solve Class 10, Chapter 5, Exercise 5.4, Questions 1 to 3 step by step. These equations have higher powers of the variable, so we substitute a new variable like y to reduce them to a quadratic equation. Then we solve it using the quadratic formula and find the values of the original variable. 📌 What you'll learn: ✔ How to choose the right substitution, like y = x² ✔ How to rewrite the equation as ay² + by + c = 0 ✔ How to use the quadratic formula x = (−b ± √(b² − 4ac)) / 2a ✔ How to go back to the original variable and get all the solutions ✔ How to write a clean exam study answer۔ 👍 If this helped you, like the video, share it with your classmates and subscribe to STEM Genius Point for more fully solved exercises. 💬 Stuck on a question?
