Since the binomial is elevated to a even power, we have that:

Now we need to remember The Binomial Theorem

We now apply the previous formula to our particular problem, obtaining:

$Find the coefficient of {x}^(2) {y}^(2)in the expansion of ( - 6x - y)^(4)Give answer-example-1$

$Find the coefficient of {x}^(2) {y}^(2)in the expansion of ( - 6x - y)^(4)Give answer-example-2$
