Best ResponseYou've already chosen the best response.0you can factorize u^24 to (u2)(u+2) and next exp as u(u2) cancel out (u2) from denom and num

Best ResponseYou've already chosen the best response.0u + 2, u is not 2?

Best ResponseYou've already chosen the best response.3we have a perfect square on the numerator... can we split that up in the form of (a+b)(ab) where a = x and b =2?!

Best ResponseYou've already chosen the best response.3whatttttttttttttttttttt! pop quiz what the square root of 4

Best ResponseYou've already chosen the best response.3yes... whenever we have a perfect square we can split (a^2b^2) in the form of (a+b)(ab)

Best ResponseYou've already chosen the best response.3so since a = x and b = 2 what is the numerator... we can split it up in the form of (a+b)(ab)

Best ResponseYou've already chosen the best response.3what do you have for the numerator first?

Best ResponseYou've already chosen the best response.3no you're missing something I'll give an example (x^29) =(x+3)(x3) now follow that pattern with u^24

Best ResponseYou've already chosen the best response.3it's 3 on the example because the square root of 9 is 3

Best ResponseYou've already chosen the best response.3(u^24) the term u^2 is a perfect square and the same goes for 4 so the square root of u^2 is u and the square root of 4 is 2 whenever we have something like u^2  4 , it is a perfect square polynomial in the form of (u^24) = (u+2)(u2)

Best ResponseYou've already chosen the best response.3now for the denominator u^2 can also be written as uu... eventually you may be required to be swift in factoring and taking out like terms u^22u I can take a u out and it becomes u(u2) to see it easier uu2u and since we have a u on the left and u on the right we can take that out

Best ResponseYou've already chosen the best response.3so now we have (u+2)(u2) / u(u2) so what does the numerator and denoiminator have in common that we can remove.

Best ResponseYou've already chosen the best response.3yes! so we have (u+2)/(u)

Best ResponseYou've already chosen the best response.0i think i understand better now

Best ResponseYou've already chosen the best response.3hmm if we have to simplify further we can split (u+2)/(u) into 2 fractions because they have the same denominator u/u +2/u 1+ 2/u or we can leave the answer like that

Bananas1234

Best ResponseYou've already chosen the best response.0based on my options i think its ok to leave it

Best ResponseYou've already chosen the best response.0so is it u +2/u, u is not 0 or u +2/u, u is not 2, u is not 0 ? and how do i find out?

UsukiDoll

Best ResponseYou've already chosen the best response.3the denominator of u is the whole entire thing \[\frac{u+2}{u}\]

UsukiDoll

Best ResponseYou've already chosen the best response.3since they share a single denominator we can split it up into 2 different fractions or leave it as is.

Best ResponseYou've already chosen the best response.3\[\frac{u}{u} +\frac{2}{u} \rightarrow 1 + \frac{2}{u}\]

Best ResponseYou've already chosen the best response.3we can't have u = 0 .. because anything divided by 0 is undefined.
