Best ResponseYou've already chosen the best response.0We need on "fraction" for each factor in the bottom. A B 3  +  =  (2x+1) (3x2) (2x+1)(3x2) is thsi correct?

Best ResponseYou've already chosen the best response.0After we split it up into its "baser" units, we can try to "resolve" it.

Best ResponseYou've already chosen the best response.0the bottoms become redundant and we want the tops to equal out.

Best ResponseYou've already chosen the best response.0A(3x2) + B(2x+1) = 3 lol.... they are really rhetorical, but I do tend to mess up alot ;)

Best ResponseYou've already chosen the best response.0for the set up only where should i stop?

amistre64

Best ResponseYou've already chosen the best response.0you should stop when all the possible "denominators" are accounted for: for example, if the denominator is (x+2)^3 we need to account for.. (x+2) and (x+2)^2 and (x+2)^3 as possible denominators in our setup

Best ResponseYou've already chosen the best response.0what do we do for 3 terms in numerator?

amistre64

Best ResponseYou've already chosen the best response.0the 3 in the numberator is what we use to set up the condition for our "unknowns". A + B have to end up equaling 3 in the end.... its our goal, our guide, our calibration.

amistre64

Best ResponseYou've already chosen the best response.0If we get stuff like x^2(A+B) and there is no value for x^2 in our numberator, we set it up by 0x^2

Best ResponseYou've already chosen the best response.03x^2 +x 1  (x^2+2) (x^2+1) can we factor the bottom any more? I dont see that we can....

Best ResponseYou've already chosen the best response.0A B 3x^2 +x 1  +  =  (x^2+2) (x^2+1) yadayada Try to "solve" by getting like denominators now :) like normal...

amistre64

Best ResponseYou've already chosen the best response.0A(x^2+1) +B(x^2+2) = 3x^2 +x 1   yadayada yadayada makes sense?

Best ResponseYou've already chosen the best response.0x^2(A)+1(A) +x^2(B)+2(B) = 3x^2 +x 1 x^2(A) + x^2(B) +(A+2B) = 3x^2 +x 1 x^2(A+B) + (A+2B) = 3x^2 +x 1  x^2(A+B) = 3x^2 A + B = 3
