The first one is \[\Large \frac{8}{ab} + \frac{6}{b}\] right?
yes.
what is the LCD in this case?

i don't know.
we have ab as the first denominator and b as the second denominator
do you see how the LCD would be ab?
no.
:( I'm really bad at math. I'm sorry..
maybe replace a and b with numbers
say a = 2 b = 3
okay.
ab = 2*3 = 6
i understand that.
if we had 1/6 + 1/3, what would the LCD be?
6
yes because we can multiply the denominator 3 by 2 to get 6
we can multiply top and bottom of 1/3 by 2 to get 2/6 1/6 + 1/3 turns into 1/6 + 2/6
from there you add straight across and leave the denominator alone
mhm.
the same idea applies here we multiply top and bottom of the second fraction by 'a' \[\Large \frac{8}{ab} + \frac{6}{b}\] \[\Large \frac{8}{ab} + \frac{6{\color{red}{a}}}{b{\color{red}{a}}}\] \[\Large \frac{8}{ab} + \frac{6a}{ab}\]
then you add the numerators and place that over the denominator
okat.
now I'm lost.
where at?
how do we find the answer? or did we already find it and i was lost before then? i thought I've been following.
do you see why I multiplied top and bottom of the second fraction by 'a'?
I wanted to get every denominator equal to the LCD 'ab'
okay
there's one more step to go
alright.
What does \[\Large \frac{8}{ab} + \frac{6a}{ab}\] simplify to?
8/ab + 6/ab
i really am lost.
8/ab+6/b
just add up the numerators \[\Large \frac{8}{ab} + \frac{6a}{ab}=\frac{8+6a}{ab}\] this is possible because the denominators are both equal to ab
okay. now how would we do the second one?
The second one is \[\Large \left(\frac{3t^2}{t+2}\right)\times\left(\frac{t+2}{t^2}\right)\] right?
t+2 on the sec on one are in a parenthesis.
and in the first one. its like parenthesis insides of themselves.
ok so this? \[\Large \left(\frac{3t^2}{(t+2)}\right)\times\left(\frac{(t+2)}{t^2}\right)\]
yes that is correct.
first notice this cancellation \[\Large \left(\frac{3{\color{red}{\cancel{\color{black}{t^2}}}}}{t+2}\right)\times\left(\frac{t+2}{{\color{red}{\cancel{\color{black}{t^2}}}}}\right)\] the t^2 terms will go away leaving just \[\Large \left(\frac{3}{(t+2)}\right)\times\left(\frac{(t+2)}{1}\right)\]
ok what is the next step
then the (t+2) terms also cancel \[\Large \left(\frac{3}{{\color{red}{\cancel{\color{black}{(t+2)}}}}}\right)\times\left(\frac{{\color{red}{\cancel{\color{black}{(t+2)}}}}}{1}\right)\]
I'm sure you see how to finish
so its 3?
yep
thats the easiest thing I've ever seen
