Question

If 1 is one of the zeroes of the polynomials having zeroes -2and5

Answer 1

Answer:

Then it is a cubic polynomial as it has three zeroes.

Step-by-step explanation:

The polynomial therefore is (x - 1) (x + 2) (x - 5)

(x - 1) (x + 2) (x - 5)

(x2 + x - 2) (x - 5)

x3 + x2 - 2x - 5x2 - 5x + 10

x3 - 4x2 - 7x + 10
