Best ResponseYou've already chosen the best response.07w^2+3w4=7w^2+7w4w4 =7w(w+1)4(w+1) =(7w4)(w+1) now ur question becomes:(7w4)(w+1)/(w+1)=(7w4)

Best ResponseYou've already chosen the best response.0thats not what i asked. i asked how to divide them. idk how to do that

Best ResponseYou've already chosen the best response.0That is exactly what you asked. A better question might be: I don't understand, can you explain, please?

Best ResponseYou've already chosen the best response.0no its not i asked to divide them not factor them

Best ResponseYou've already chosen the best response.0The point they are both making is that the most expedient way of dividing the two is to factor 7w^2 + 3w  4 and then divide.

Best ResponseYou've already chosen the best response.0Here's the long division version, however:

Best ResponseYou've already chosen the best response.0Ok, well, the most straightforward way to see it is, above. You're dividing 7w^2 + 3w  4 by w + 1. Now, w + 1 has two parts, the w, and the 1. That means you'll have to deal with only two parts of 7w^2 + 3w  4 at a time. We start at the left, with 7w^2 + 3w. We concentrate on getting the w to turn into a 7w^2, which is why we use 7w. That gives us 7w(w + 1) = 7w^2 + 7w. Then we subtract that from the full polynomial, 7w^2 + 3w  4. That leaves us with 7w  4.

Best ResponseYou've already chosen the best response.0Sorry, that leaves us with 4w  4. Now that's another two parter, so we focus on 4w. We can turn w into 4w by multiplying by 4. So we, have 4(w + 1) = 4w  4. That's the same as 4w  4, so they cancel out, and we've successfully divided the two polynomials.

Best ResponseYou've already chosen the best response.0Ok, so the point of dividing 7w^2 + 3w  4 by w + 1 is to find something where, if we multiply it by w + 1, we get 7w^2 + 3w  4. Right?

Best ResponseYou've already chosen the best response.0Ok, so we start by seeing how we can get w to turn into 7w^2. We can do that by multiplying w by 7w.

Best ResponseYou've already chosen the best response.0Once we've found that we want to multiply by 7w, we multiply all of (w + 1) by it, and we get 7w^2 + 7w. Then, to reach the next step, we subtract it from the original polynomial, which is 7w^2 + 3w  4. 7w^2  7w^2 = 0 3w  7w = 4w  4  0 = 4 So we end up with 4w  4.

Best ResponseYou've already chosen the best response.0Then, we need to find a way to turn w into 4w. We can do that by multiplying by 4.

Best ResponseYou've already chosen the best response.0We do the same thing as above, multiply w + 1 by 4, which gives us 4w  4, then subtract that from the remainder from the last subtraction, which was also 4w  4: 4w  (4w) = 0 4  (4) = 0 And so we have 7w (the first part) + (4) (the second part) as our result. This is the same as 7w  4.
