Question

Find the polynomial f(x) that has the roots of –2, 3 of multiplicity 2. Explain how you would verify the zeros of f(x).

Answer 1

\[f(x) =(x+2)^{2}(x-3)^{2}\]

Answer 2

anyone? /:

Answer 3

oh thanks myko! (:

Answer 4

just multiply

Answer 5

one more question if you wanna give it a try?

Answer 6

i will make my best, :)

Answer 7

When asked to find the zeros of the function r(t) = 5t3 – 8t2 + 7t + 2 which task would you complete first - Rational Root Theorem or Descartes’ Rule of Signs? Use complete sentences to explain your reasoning.

Answer 8

sry, no idea what rational root theorem is. Just would use Ruffinim, since this is a cubic equation

Answer 9

ahh okay thanks anyways c:
