Question

What is the quotient?

7x – 10 – 19/x-1
7x + 4 – 5/x-1
7x – 10 + 1/x-1
7x + 4 – 13/x-1

Answer 1

correct answer is
7x + 4 – 5/x-1

Answer 2

B)
`7x + 4 -(5)/(x-1)`

Explanation:

Here we have to divide 7x^2 - 3x - 9 by (x - 1).

Step 1: We need to get rid of 7x^2 that is the leading coefficient.

We need to add 7x in the quotient part and multiply with (x -1 )

7x(x - 1) = 7x^2 - 7x

Now we have to subtract.

Step 2: We got dividend is 4x - 9

Now we have to get rid off 4x, so we have to add +4 in the quotient part and multiply with (x -1)

4(x -1) = 4x - 4

Now we have to subtract

So we got the quotient = 7x + 4 and the remainder is -5

The answer is = 7x +4 -
`(5)/(x-1)`
