Find all rational roots for p(x)=0 p(x)=6x^4-13x^3+13x^2-39x-15 a. no rational roots b. 1/2,1/3 c. 5/2,1/3 d. -1/2,5

Answer

C. (5/2, -1/3)

Step by step explanation

Here we use the rational root theorem.

The possible roots are

+1, +3, +5, +15, +1/2, +3/2, +5/2, +15/2, +1/3, +5/3, +1/6 and +5/6

We have to use the synthetic division to find the correct root of this function.

Here the roots are 5/2 and -1/3

Others are not roots of this function.

Let's check x = 5/2  with synthetic division.

5/2)   6   -13   13   -39   -15

-               15    5    45    15

             6     2   18     6     0

Similarly x = -1/3 is also root of this function.

C. (5/2, -1/3)
