Question

The number of polynomials having zeroes as -2 and 5 ​

Answer 1

Answer:

(d) Let p (x) = ax2 + bx + c be the required polynomial whose zeroes are -2 and 5. Hence, the required number of polynomials are infinite i.e., more than 3.

Answer 2

Answer:

sum of zeroes =-2/1+5/1=-3/1

-3 is cofficient of x and 1 is cofficient of x^2

product of zeroes =-2×5= -10/1

-10 is constant term and 1 is cofficient of x^2

thus the quadratic equation is x^2-3x-10
