Verify that the numbers given alongside of the cubic polynomials below are their zeroes. Also, verify the relationship between the zeroes and coefficients in each case: Let p(x) = 2x3+x2–5x + 2 Comparing the given polynomial with ax3 + bx3 + cx + d, we get Now,
and ∴ are the zeroes of Hence, verified.Here, we have Now, and Hence verified. |
