My problem states to factor completely:
49c+56c+16
Nothing can be factored out as it is. So I took the product of 49 & 16 = 784 and two integers whose products equal 784 and sum equals 56 is (28)(28)
Yet when I go to factor, it's not adding up. Maybe I am confusing the steps?
49c^{2}+28c+28c+16
28c(c+21c) ?
I am not sure what I am suppose to do actually...
Hello, Kibbygirl!
Factor completely: .
Nothing can be factored out as it is.
So I took the product of 49 & 16 = 784
. . and two integers whose products equal 784 and sum equals 56 is (28)(28).

. This is correct!
28c(c+21c) ? .But what is this?
You are supposed to "factor by grouping".
Are you familiar with it?
You have: .
Factor the terms "by pairs".
. . You can factor from the first two terms
. . You can factor from the last two terms.
Then you have: .
Note that the term groups have on common . . . factor it out!
And we have: .
See how it works?
