How do you simplify #3/(x-4) * (x-4)/(12(x-7))#?

Answer 1

#1/(4(x-7)#

#3/((x-4)) * ((x-4))/(12(x-7)) " put in brackets "#

You may only cancel across or through a X sign, and NOT into a bracket - you may cancel a whole bracket. Cancel factors that are the same.

#cancel3/(cancel(x-4)) * (cancel(x-4))/(cancel12^4(x-7))#
#1/(4(x-7)#

Answer 2

To simplify the expression 3/(x-4) * (x-4)/(12(x-7)), we can cancel out the common factor of (x-4) in the numerator and denominator. This leaves us with 3/12(x-7). Simplifying further, we can divide both the numerator and denominator by 3, resulting in 1/4(x-7). Therefore, the simplified expression is 1/4(x-7).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
