No idea how to solve this. Please help.

Please review by TN 5 (part 1) Video 2 if you are having trouble with this problem. My examples 2, 3, and 5 in that video go through exactly how to do a problem like this. Consider f(a) = (x+2)(1-2x) - x+2 + 1-2x . If you are curious how I got the second expression from the first, it was partial fractions, but you don't need to know that for this problem (just making a note that this is how you find Taylor series for rational functions). Here is what you need to do: . Find the Taylor series for -1, based at b = 0, practice writing it in sigma notation. . Find the Taylor series for -, based at b = 0, again practice writing it in sigma notation. . Find the Taylor series for x42 + 1-2x 2 - based at b = 0, see if you can write it using only one sigma sign. Now type in the coefficients of the first three non-zero terms of your final answer. These will just be numbers you are typing in the spaces provided. + 1-2x = 5/2 + 15/4 65/8 a2 + .. Also give the interval of convergence for you final answer by typing in the correct number below. (you can enter your answers as reduced fraction like "65/8" or you can type in a decimal rounded to three digits. I coded it to accept all things like 5/2 or 2.5 or 2.50 or 2.500. But it won't accept 2.5000 or 10/4, sorry the system is picky, but I have coded for all normal ways of typing this in.)
