question starts with P(x) = -2x^3(x-1)(2x^2+1). I was then supposed to express the polynomial in general form and got -4x^6 + 4x^5 - 2x^4 + 2x^3. Then asked to determine the left and right end behavior which I did. What I'm suck on is the final part which is "Find the x-intercepts, if any.". I know im supposed to set y to zero, but I cant figure this one out. I cant find out how to factor it, im stuck. thanks :)

    Hi , i'm trying to integrate 1/(2+6x+9x^2). I know we're supposed to complete the square as part of our steps and I got 1/(3x+3)^2-7. I'm not sure if i'm correct with what I did and i'm also stuck from there. Your help would be appreciated.

  • #3 Choose the end behavior of the graph of the polynomial function

    #3 Choose the end behavior of the graph of the polynomial function. f(x) -x(x-3)(5x+2), I think I have to foil to get -5x^3-2x^2+15x+6 So I think this one rises to the left and falls to the right. Please let me know if I did these correctly. Thanks

Let We could attempt to solve this problem in the same manner as we did problems in the previous si However, we can arrive at the solution much faster by using the given hint.
