Ex 4.3 Q2 (i) & (ii) | Find k for Equal Roots | Class 10 Maths NCERT

Ex 4.3 Q2 (i) & (ii) | Class 10 Maths NCERT New Book | by NCERT Solutions by Indramani singh "This video gives you the complete, step-by-step solution for Question 2 (i) and (ii) of Exercise 4.3 from the New NCERT Class 10 Maths textbook (Chapter 4: Quadratic Equations). 🚀 This is a very important CBSE board exam question! We solve for the unknown value 'k' by using the fundamental condition for equal roots. Key Concept Used: • A quadratic equation \mathbf{ax^2 + bx + c = 0} has two equal roots if and only if its Discriminant (\mathbf{D}) is equal to zero (\mathbf{D = b^2 - 4ac = 0}). We solve the following equations for 'k': 1. Ex 4.3 Q2 (i): 2x^2 + kx + 3 = 0 2. Ex 4.3 Q2 (ii): kx(x - 2) + 6 = 0 Master this simple condition to guarantee full marks on this type of question!
