Question

What must be subtracted from 4x^4-3x^3-6x^2+2x+6 so that the result is exactly divisible by 2x^2+x-1 ? Class 9 Polynomials . Please help me.

Answer 1

Answer:

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.

Answer 2

Step-by-step explanation:

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