Access answers to ncert exemplar class 10 maths chapter 2 polynomials exercise 2.1. choose the correct answer from the given four options in the following questions: 1. if one of the zeroes of the quadratic polynomial (k–1) x 2 k x 1 is –3, then the value of k is (a) 4 3 (b) 4 3. 2 3 (d) 2 3; solution: (a) 4 3. explanation: according. These are the roots of quadratic polynomial. sum of zeros = √5 − √5 = 0 = − coefficient of x coefficient of x2. product of zeros = − √5 × √5 = − 5 = − 5 1 = − constant term coefficient of x2. so, the zeros are x = √5, − √5 x = √5,−√5 and the required relationship is verified. example 3.
