If a be the number of students who take junk food, B be the number of students who take healthy food such that alpha > beta and a and B are the zeroes of the quadratic polynomial f(x) = x ^ 2 - 7x + 10 , then answer the following questions:(i) Name the type of expression of the polynomial in the above statement? (a) quadratic (b) cubic (c) linear (d) bi-quadratic (ii) Find the number of students who take junk food. (a) 5 (b)2 (c) 7 (d) None of these (iii) Find the number of students who take healthy food. (a) 5 (b) 2 (e) 7 (d) None of these (iv) Find the quadratic polynomial whose zeros are -3 and -4. (a) 1 ^ 2 + 4x + 2 (c) x ^ 2 - 7x + 12 (b) x ^ 2 - x - 12 (d) None of these (v) If one zero of the polynomial x^ 2 . 5x + 6 is 2 then find the other zero. (i) 6 (ii) -6 18. Case Study based-2: (iii) 2 (d) None of these
