Verify that the number given alongside of the cubic polynomials below are their zeroes. Also verify the relationship between the zeroes and the coefficients in each case.
i] `2x^(3) + x^(2) - 5x + 2, (1)/(2),1,-2`
ii] `x^(3) - 4x^(2) + 5x - 2, 2,1,1`

Text Solution

Verified by Experts

The correct Answer is:
(i) Therefore, `(1)/(2),1 `, and -2 are the zeroes of p(x)
ii] Hence, the relationship between the zeroes and the coef-ficients is verified.
