Question

What must be subtracted from 4x^4−2x^3−6x^2+x−5 so that the result is exactly divisible by 2x^2+x−1?


Pls help I have test on sunday

Answer 1

Answer:

Let's divide 4x⁴ - 2x³ - 6x² + x - 5 by 2x² + x - 1.(see in attachment)

We get; (-6)

Hence, (−6) should be subtracted from (4x⁴ − 2x³ − 6x² + x − 5) so that the resulting polynomial is exactly divisible by (2x² + x – 1).
