So firstly, factor out the GCF, or greatest common factor. To find the GCF, list the factors of every term and the greatest one they all share is their GCF. In this case, the GCF is "a":

$a(a^2+4a+4)$

Next, we are going to apply the square of binomials rule in this situation, which is $(x+y)(x+y)=x^2+2xy+y^2$ In this case:

$a^2+4a+4=(a+2)(a+2)\\\\a(a+2)(a+2)$

<u>Your final answer is $a(a+2)(a+2)$ </u>

galina1969 [7]

Answer:

270725 different ways

Step-by-step explanation:

The problem tells us that the order of the letters does not matter. Therefore, in the combination the order is NOT important and is signed as follows:

C (n, r) = n! / r! (n - r)!

We have to n = 52 and r = 4

C (52, 4) = 52! / 4! * (52-4)! = 52! / (4! * 48!) = 270725

Which means that there are 270725 different ways in total to make that raffle
