HELP! I need help finishing this problem!
Here is the question as posed to me in my homework (actually... it's a take home test, so its even more important!)
f(x)= 6x^5 + 5x^4 - 35x^3 - 21x^2 + 51x + 18.
A: Find all of the zeros of f(x).
B: Write f(x) in factored form.
C: Draw an approximate sketch of f(x)
-2, -1/3, 3/2 are the three zeros that i have found using synthetic divison. The remaining equation i have left is 6x^2 - 18 which I have factored into 6(x^2 - 3). Is this the correct action to take (as in factoring it out) and what would be the remaining two zeros? Would it be -3 and 3? How do I write f(x) into factored form? And how would I draw an approximate sketch of that? IF someone could help me out... I would be forever in debt to them. THANKS IN ADVANCE!
