This involves grouping "like" terms. Terms containing no variables are "like" terms. Terms containing the same variable expression are like terms, for example terms containing w

Grouping like terms, we get

(4w

Please note that we had to pay attention to the signs.

Now, we can factor within each of these groups ... (we just add the constants)

w

2w

^{2}.Grouping like terms, we get

(4w

^{2}- 2w^{2}) + (-4w - 3w) - 8 + 6Please note that we had to pay attention to the signs.

Now, we can factor within each of these groups ... (we just add the constants)

w

^{2}(4 - 2) + w(-4 -3) - 22w

^{2}-7w -2 (this is the result of carrying out the arithmetic)
