Hi dmatinho,

The factoring involved in this question is a bit more complicated than normal since we're factoring out a "term" and not just an individual number or variable.

For example, factoring the following is pretty easy:

2X - 4

2(X - 2)

Since you can "see" that there's a "2" in both terms

In this prompt, we have to factor out (2T-1) from each of the terms:

[(2T-1) + (2T-1)^2]/(2T-1)

I'm going to split the numerator into 2 'pieces'....

(2T-1) and (2T-1)^2

Now, think about how you would factor (2T-1) out of each piece...

(1)(2T-1) and (2T-1)(2T-1)

Next, when we completely factor out (2T-1), think about what's "left over"....

(2T-1)[ (1) + (2T-1)]

Inside the bracket, the +1 and the -1 'cancel out', leaving us with...

(2T-1)(2T)

The last step is to deal with the denominator of the original fraction....

(2T-1)(2T)/(2T-1)

That denominator cancels out the same term in the numerator, leaving us with....

2T

The approach that you took is fine; you're ultimately just breaking the fraction into two pieces and then combining the results later.
