Answer asap! show all work! will give brainliest! 1) divide using long division ( show all work) (x^2 - 13x - 48) ÷ (x + 3) 2) divide using long division ( show all work) (3x^3 - x^2 - 7x + 6) ÷ (x + 2) 3) using long division determine whether (x + 2) is a factor of x^3 + 3x^2 - 10x - 24 ( show all work)

1) , and . Subtracting this from the numerator gives a remainder of

, and . Subtracting this from the previous remainder gives a new remainder of

This means that

2) , and . Subtracting this from the numerator gives a remainder of

, and . Subtracting this from the previous remainder gives a new remainder of

, and . Subtracting this from the previous remainder gives a new remainder of

This means that

3) will be a factor of if dividing the latter by leaves a remainder of 0.

, and . Subtracting this from the numerator gives a remainder of

, and . Subtracting this from the previous remainder gives a new remainder of

, and . Subtracting this from the previous remainder gives a new remainder of

and since the remainder is 0, is indeed a factor of .

a) 7x=7
