Question

5. If the quotient on dividing 2x4 - 7x3 - 13x2 + 63x - 48 by 2x - 1 is r3 - ax2 + bx + 55
then find a, b and also find the remainder.
​

Answer 1

Answer:

We divide 2x

4

−7x

3

−13x

2

+63x−48 by (2x−1) as shown in the above image:

From the division, we observe that the quotient is x

3

−3x

2

−8x+

2

55

and the remainder is −

2

41

.

Hence, the quotient is x

3

−3x

2

−8x+

2

55

and the remainder is −

2

41

.
