Question

What must be subtracted from 4x4 - 2x3 - 6x2 + x-5 so that the result is exactly divisible by 2x2 + x-1?
​

Answer 1

Answer:

Hi

Step-by-step explanation:

We divide 4x  

4 −2x  

3 −6x  

2 +x−5 by 2x  

2 +x−1

as shown in the below image:

From the division, we observe that the quotient is 2x  

2  −2x−1

and the remainder is −6.

Hence, −6 should be subtracted from 4x  

4 −2x  

3 −6x  

2 +x−5

so that result is exactly divisible by 2x  2  +x−1.
