Yes, so what is it u want to do?

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

OK, 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?

LCD 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.

Okay. Thank you. I know the answer is (1,0). I just wanted to make sure I was on the right path.

U should also note that x=3 and x = 2 are not defined for this equation.

Could you please explain the shorter way of doing this type of equation.

estudier Group TitleBest ResponseYou've already chosen the best response.1
If 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

Wow that is much quicker! Thank you so much

The 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....

Could I use this shorter way for this equation as well? (see drawing)

Yes, u can.

Thanks. When I add the terms on the LHS I get (z+1) / (z6). Is this correct?
 one year ago

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