Verify that the numbers given alongside of the cubic polynomials below are their zeroes. Also verify the relationship between the zeroes and the coefficients in each case:
Therefore, , 1, and −2 are the zeroes of the given polynomial.
Comparing the given polynomial with , we obtain a = 2, b = 1, c = −5, d = 2
Therefore, the relationship between the zeroes and the coef...
