BaLLatris [955]

Answer:

The quotient is: x-7

and remainder is : -300

Step-by-step explanation:

We need to divide $X^3+43-49x-7x^2$ by $x^2-49$

First arrange the term $X^3+43-49x-7x^2$ in terms of ascending order of x.

Arranging we get:

$x^3 - 7x^2 -49x + 43$ \ $x^2-49$

The division steps are shown in figure attached.

The quotient is: x-7

and remainder is : -300
