Question

Divide by using long division (x^2+5x-28) /(x-3)

Answer 1

its just like normal division



multiply the division by x... what do you get?

Answer 2

oops multiply the divisor by x... what do you get

Answer 3

Idk :/

Answer 4

so you have

\[x(x - 3) = ?\]

what is the expansion...?

Answer 5

x^2-3x?

Answer 6

thats great so it works like this



does that make sense..?

Answer 7

but there is still a little bit more to do

Answer 8

No i've never learned this

Answer 9

Is it x+8 - 4/x-3?

Answer 10

bring down the + 28

and multiply the division by 8



so the quotient is (x + 8) and the remainder is 52/(x - 3)

Answer 11

How do you write it out because that's not one of my choices?

Answer 12

well it may be like the left hand side... and I just saw a typo in my calculations it should be -28 and not + 28 in the original question.

(x - 3)(x+8) - 4 = x^2 + 5x - 28

Answer 13

the alternative is (x +8) - 4

Answer 14

Ok thank you.
