SUMMARY

The polynomial division of (x^3-15x-7) by (x^2-3x-3) is performed using long division. The process involves subtracting the product of the divisor and the leading term of the dividend, resulting in a remainder of -3x + 2. The final expression can be represented as (x + 3)(x^2 - 3x - 3) - (3x - 2) = x^3 - 15x - 7, confirming the division is accurate. This method is essential for solving polynomial equations efficiently.

Ok, I have been trying to divide this polynomial.

(x^3-15x-7)/(x^2-3x-3)

After I factor the first part I get stuck. This is last problem on my homework and is due in less than an hour. Please some one help me out. Thanks

(x^3-15x-7)|x^2-3x-3
-
x^3-3x^2-3x
------------
3x^2-12x-7
-
3x^2-9x-9
------------
-3x+2

so the answer is (x+3)*(x^2-3x-3)-3x+2=x^3-15x-7

im sorry for my long division it's just the lack of other way of doing it.
