Answer:
To factor out the GCF from the given expression, we can use the distributive property. This property states that we can distribute a common factor to all of the terms in an expression by multiplying the common factor by each term separately. In this case, the common factor is n, so we can distribute it to each term by multiplying it by -26, 7, and 13:
(-26n * n) + (7n * n) + (13n * n)
This gives us:
-26n^2 + 7n^2 + 13n^2
We can then combine like terms by adding the coefficients of n^2:
(-26 + 7 + 13) * n^2
This gives us the final result:
-6 * n^2
Therefore, we can factor out the GCF of -6n^2 from the given expression.
