Question

19. A mathematics teacher of class Xth writes two different polynomials (as shown in figure). And ask some questions from students, then answer the following questions. 7(x)=(3x^ 2 -5)(x^ 2 -3x+7).; + k + 10; a(x) = 3sigma - 5 (i) Iff(x) is completely divisible by g(x) then find the value of k. a)-8; (c) - 10 (b) - 9 (d )-11 (ii) Write the correct polynomial f(x) (a) 3x ^ 4 - 9x ^ 3 + x ^ 2 + 15x + 10 (b) 3x ^ 4 + 9x ^ 3 - x ^ 2 - 15x - 10 (c) 3x ^ 4 - 9x ^ 3 + x ^ 2 + 15x - 10 (d) None of the above (iii) Find the other factors of f(x) (a) (x + 1); (x - 2) (b) (x - 1), (x + 2) (c) (x - 1), (x - 2) (d) (x + 1), (x + 2) (iv) Find the other two zeroes of f(x) (a) 1, 2 (c) - 1, - 2 (b) 2, 3 (d) 1, - 2 (v) If a and B are the zeroes of any polynomial, then polynomial is written as (a) x ^ 2 + (alpha + beta) * x + alpha*beta (b) x ^ 2 - (alpha + beta) * x + alpha*beta (c) x ^ 2 - (alpha + beta) + sigma*beta * x (d) None of the above​
