Best ResponseYou've already chosen the best response.0I think it's 4x + 542x + 10/ x^2  x 5

Best ResponseYou've already chosen the best response.04x3 + x2 + 17x – 15 is the numerator and x2 – x – 5 is the denominator

Best ResponseYou've already chosen the best response.0Write it like a long division problem.. The 4x^3 part on the inside. You ask yourself x^2 times what gives you 4x^3 that answer is 4X so that is what you put above the 4x^3 in the answer. This is step 1.

Best ResponseYou've already chosen the best response.0Once you put 4x up on top.. you multiply it by every term in (x^2  x  5) so under the 4x^3 you write 4x^3 + 4x^2 + 20x You get that by 4x(x^2  x  5) change all the signs on the bottom because you want to subtract so on the bottom you get 4x^3  4x^2  20x draw your line under this and add them up

Best ResponseYou've already chosen the best response.0the 4x^3 and the 4x^3 add to 0 so you don't write that down. the x^2  4x^2 should give you 3x^2 the 17x  20x should give you 3x then bring down the next term (15) you should see 3x^2  3x  15 on the bottom

Best ResponseYou've already chosen the best response.0Then you ask yourself x^2 times what give you 3x^2 (just like the first step) The answer is 3 so you write + 3 up in your answer next to your 4x Once you write +3 then you "distribute" with the (x^2  x  5) and you write down "on the bottom" 3x^2  3x  15 because we are subtracting.. change all of the signs 3x^2 + 3x + 15 and draw a line add them up.. you should get all zeros. So your answer is 4x + 3 that means (4x + 3) times (x^2  x  5) = your original 4x^3 + x^2 + 17x + 15
