Best ResponseYou've already chosen the best response.0Multiply (1), (2x/x+3), and (2x/x+2) by the LCD of (x+3) and (x+2).

Best ResponseYou've already chosen the best response.1OK, that is the long way around of solving for x. You will get to the same place at the end. I guess your teacher has told u to do it that way, right?

Best ResponseYou've already chosen the best response.1LCD of (x+3) and (x+2) is just (x+3)(x+2) I will leave you to it, it is not too hard to do.

Best ResponseYou've already chosen the best response.0Okay. Thank you. I know the answer is (1,0). I just wanted to make sure I was on the right path.

Best ResponseYou've already chosen the best response.1U should also note that x=3 and x = 2 are not defined for this equation.

Best ResponseYou've already chosen the best response.0Could you please explain the shorter way of doing this type of equation.

Best ResponseYou've already chosen the best response.1If you add the terms on the left side > (x3)/(x+3) = 2/(x+2) Cross multiply > (x3)(x+2) = 2(x+3) > x^2 x 6 = 2x  6 > x^2 + x = 0 > x( x +1) = 0 > x = 0 or 1

Best ResponseYou've already chosen the best response.0Wow that is much quicker! Thank you so much

Best ResponseYou've already chosen the best response.1The other way reminds you that the original equation is not defined for x=3 and x = 2 But with some practice you will not need reminding....

Best ResponseYou've already chosen the best response.0Could I use this shorter way for this equation as well? (see drawing)

Best ResponseYou've already chosen the best response.0Thanks. When I add the terms on the LHS I get (z+1) / (z6). Is this correct?

estudier

Best ResponseYou've already chosen the best response.1No, (z+1) + 1*(z6) / (z6) = (2z5) / (z6)
