7. Use the numbers in the last row to write the quotient, plus the remainder above the divisor.
The degree of the first term of the quotient is one less than the degree of the first term of the dividend.
The final value in this row is the remainder.

We write the result of long division as
dividend$\div$divisor=quotient +$\displaystyle \frac{remainder}{divisor}$
c=$-1$, so we were dividing with (x+1)...OK
The first row has 4 coefficients, representing the dividend:
$3x^{3}-4x^{2}+2x-1\qquad...$(degree =3) $OK$
The quotient is given in the last row as
$3x^{2}-7x+9\qquad... $(degree =2) $OK$
The final value is the remainder, $-10$.... OK
