Answer 1

D d^3 - 4d^2 - 8d - 15 R-13

Explanation:

This is done the same way as long division.

Red Box - The equation.

Orange Box:

How many times is d going into d^4? d^3 times

- 2 * d^3 = -2d^3

Minus that from the original equation:

(d^4 - 6d^3) - (6d^4 - 2d^3) = (d^4 - d^4) - (6d^3 - 2d^3) = - 4d^3.

Write the resultant underneath.

Yellow Box:

How many times is d going into - 4d^3.? -4d^2 times

- 2 * -4d^2 = -8d^2

Minus that from the resultant equation:

(-4d^3 + 0d^2) - (4d^3 - 8d^2) = (-4d^3 - 4d^3) - (0d^2 - 8d^2) = - 8d^2

Green Box:

How many times is d going into - 8d^2.? -8d times

- 2 * -8d = -16d

Minus that from the resultant equation:

(-8d^2 + d) - (-8d^2 -16d) = (-8d^2 - - 8d^2) - (d - 16d) = (- 8d^2 + 8d^2) - (d - 16d) = -15d

Blue Box:

How many times is d going into - 15d.? -15 times

- 2 * -15 = 30

Minus that from the resultant equation:

(-15d + 17) - (-15d - 30) = (- 15d - - 15d) - (17 - 30) = (-15d + 15d) - (17 - 30) = -13

You have a remainder of 13.

Answer 2

Check the picture below.

notice, we firstly, need to get a value that will "mimic" the first term in our dividend, then we negativize the whole expression -(...), in order to get the quotient.

so for the first one, for example in order to get "something" * d = d⁴, well that something = d³, d³ * d = d⁴, and then -(d⁴....), and we do so for each row down below, to get the quotient.

another thing to notice, the dividend has to be in descending order, in this case, we're missing our fellow d², but is really not missing, it just has a 0 as its coefficient, thus 0d², notice in green.
