 Question 656066: a. List all possible rational zeros. b. Use synthetic division to test the possible rational zeros and find an actual zero. c. Use the quotient from part (b) to find the remaining zeros of the polynomial function. f(x)= x^3+x^2-4x-4 Click here to see answer by nerdybill(7090)

 Question 656143: list all the possible rational zeros of f(x)=2x^3-5x^2+3x-1 Click here to see answer by Edwin McCravy(9716)

 Question 656189: Find the product:((-1/3)x^2-1/3)((1/2)x+1/4) I'm not sure how to start this problem. I know in dividing you would separate the numbers from the letters and exponents. So on this problem I have tried to do -1/3*1/2*-1/3*1/4=(1/72) then multiply the x^2 and the x which you cant. so i'm so lost on this one. please help! Click here to see answer by Alan3354(34674)

 Question 659552: For Each polynomial function:(a)Find the rational zeros and then the other zeros;that is, solve f(x)=0. (B) Factor f(x) into linear functions. F(x)=x^4-3x^3-20x^2-24x-8 I can find the rational functions. But I can not find the "other" zeros. Usually the "other" zeros are like 5i or square root of 5 or 5-square root of 5.
