Write the coefficients of x2 in each of the following Solution: Extra questions based on the topic Number System. 12x2 – 7x + 1 = 12x2 – 4x- 3x + 1 We have, (x + 8) (x – 10) = x2 + [8 + (-10)] x + (8) (- 10) = 2 + 0 + 0 – 0=2 Find the value of k, if x – 1 is a factor of p (x) in each of the following cases (iii) 6x2 + 5x – 6 Solutions to all NCERT Exercise Questions and Examples of Chapter 2 Class 9 Polynomials are provided free at Teachoo.
