The Deep Dive
To subtract the two fractions, we first need to find a common denominator. The denominators are
and
.
Let’s factor both denominators:
-
For
, we need two numbers that multiply to and add to . These numbers are and . So, we can factor as: -
For
, we need two numbers that multiply to and add to . These numbers are and . So, we can factor as:
Now that we have the factored forms of the denominators, we can write the expression as:
The common denominator is
. We rewrite each fraction to have this common denominator:
Now we can combine the fractions:
Now, simplify the numerator:
Thus, we rewrite the expression:
Finally, our results yield:
This is the simplified form of the original expression.
