Answer 1

Explanation:

We divide

3x

x+

7

by

(x

2

+

1)

as shown in the above image:

From the division, we observe that the quotient is

3x+

4

and the remainder is

−2x+

3

.

We know that the division algorithm states that:

Dividend=Divisor×Quotient+Remainder

We apply the division algorithm to check the answer as follows:
