Transcribed Image Text:**Question 22:**
Estuardo divided a polynomial by a linear binomial using synthetic division. His quotient is \(4x^3 - 5x^2 + 2x - 9 + \frac{4}{x+2}\). What was the divisor, the linear binomial that he divided by? How do you know?
---
To find the divisor, one must understand that in synthetic division, any remainder represents a fraction of the form \(\frac{\text{Remainder}}{\text{Divisor}}\). Here, the remainder is expressed as \(\frac{4}{x+2}\), leading to the conclusion that the divisor is \(x + 2\).
