am I right so far....
what should I do next
cancel the common factors
wait not exactly correct
for the first fraction, the upper part, you should take 6 as the common factor
now it makes sense
can you do it once again from the start, it's very messy
that answer is correct, just not in lowest terms
see the 6 and 2
combine what you have then
am I right
your other previous answer (42/2x-4) was more correct. when doing simplification, it helps to.... simplify, to see what needs to be done more clearly. for most problems you don't need to do this, but later it gets helpful to think along these lines:
basically im saying 42/2(x-4) is the same thing as 42/2 * 1/(x-4) 42/2 is pretty simple arithmetic. Once you've got that simplified, just fit that back in to the expression.. and you've got the answer. thats one of many ways to simplify things.
im a bit confused
isn't it 2(x-2)
indeed. you could also divide by two.|dw:1332401294326:dw|
really the entire point is it does not matter how you simplify, as long as you are dividing or multiplying by "1", or keeping the overall expression equal. you'll never end up with an incorrect answer this way lol
