Question

If one of the zeros of the cubic polynomial x3

+ ax2

+ bx + c is -1, then what will be the product of the

other two zeros?​

Answer 1

Answer:

Let a, p and y be the zeroes of the given cubic polynomial p(x). Hence, a product of the other two roots is 1 -a + b. Since, -1 is one of the zeroes of the cubic polynomial f(x) = x2 + ax2 + bx + c i.e., (x + 1) is a factor of f{x)
