Long division polynomials?
Using long division can you please walk me through these problems step by step:
a). (x^3-7x-6) / (x+1)
b). (x^2+4x+4) / (x+2)
thanks in advance.

a. x to the 2nd power-7x-6
b. x+2x+2
When you have just an x , divide it just by x.
If you have a number plus x, use the number and add x to the answer.

x^2 -3xy + 2y^2 + 3x - 6y - 8 | x - y + 4, x (coef for x first) - x^2 + xy - 4x ====================== -2xy + 2y^2 - x - 6y - 8 (reorder now) 2y^2 - 2xy - x - 6y -8 | x - y + 4, -2y (coef for y 2d) 2xy - 2y^2 + 8y ===================== -x + 2y -8 | x - y + 4, -a million x - y + 4 ============= y - 4 <- the relax quotient = x - 2y -a million ..... = x - 2y -a million + (y - 4)/(x - y + 4) are you particular for the coef of x? is 3? or 2? no matter if it really is two you receives a sparkling outcome :) ... = x - 2y - 2
