X =
(smaller value)
(larger value)
= X
Transcribed Image Text:Find the poles. 4х — 9 x 2 + 8 x + 7 X = (smaller value) (larger value) = X
Expert Solution
Step 1

The given transfer function is y=4x-9x2+8x+7.

The poles of the given transfer function are those values, which makes its denominator zero.

So, in order to find the poles of the given transfer function, equate its denominator to zero and simplify for x.
