WebFind the two natural numbers which differ by 5 and the sum of whose squares is 97. Solution: Let’s assume the two natural numbers to be x and x + 5. (As given they differ by 5) So from the question, x 2 + (x + 5) 2 = 97 2x 2 + 10x + 25 – 97 = 0 2x 2 + 10x – 72 = 0 x 2 + 5x – 36 = 0 (x + 9) (x – 4) = 0 x = -9 or 4 WebSolve the following quadratic equation by factorization: 1. (x – 4) (x + 2) = 0 Solution: Given, (x – 4) (x + 2) = 0 So, either x – 4 = 0 ⇒ x = 4 Or, x + 2 = 0, ⇒ x = – 2 Thus, the roots of the given quadratic equation are 4 and -2, respectively. 2. (2x + 3) (3x – 7) = 0 Solution: Given, (2x + 3) (3x – 7) = 0. So, either 2x + 3 = 0, ⇒ x = – 3/2 WebR S Aggarwal Solutions for Class 10 Maths Chapter 4 Quadratic Equations Exercise 4A Page No: 175 Question 1: Solution: A quadratic equation is an equation of the second degree.
