Question

37. Verify that -1, -3 and 5 are the zeroes of the cubic polynomial p(x) = x3 – x2 - 17x - 15
and then verify the relationship between the zeroes and the coefficients.

Answer 1

Step-by-step explanation:

when something is the zero of the polynomial, it means when substituted in the place of variable the answer becomes 0. to check whether -1,-3 &5 are zeroes we need to substitute this in the place of x. p(-1)= (-1)^3 - (-1)^2 - 17(-1) -15

-1-1+17-15=0. therefore -1 is a zero of thos polynomial.

in the same way substitute for -3 and 5 to check whether they are zeroes of this polynomial or not
