C:
Step-by-step explanation:
The simplest form of the expression below, can be found through factorization process.
We have two quadratic expression. To find their factor, we only need to apply some steps:
Factorizing
We have to find to numbers a and b that multiplied result in 6, but subtracted result in 5. We can see that and are the right numbers, because 6 times 1 equals 6, and 6 minus 1 equals 5.
Therefore,
On the other expression, we applied the same process:
; because, and
Then, we replace these factors for each expression:
Eliminating similar factors, we have:
Which is the simples form.
