Answer: 3x^2- 12x+32

Compare each term with the dividend

3x^2- 12x+32

-------------------------

x+3 | 3x^3 - 3x^2 - 4x + 3 (Compare the 3x^3to the dividend )

3x^3+ 9x^2 Multiply each term in the divisor by 3x^2

---------------------

-12x2 - 4x Subtract each term.

multiply x(-12x) = -12x2

-12x2- 36x Multiply each term in the divisor by -12x

Subtract Subtract each term.

----------------------

32x + 3 multiply x(32) = 32x

32x +96 Multiply each term in the divisor by 32

----------------------

-93

So the final answer is 3x2 - 12x + 32 with remainder -93
