Hello Julie,

Do you want to factor it?

Here you go!

b^{2}+8b+7 = (b+1)(b+7)

If you want to solve b^{2}+8b+7 = 0, then the solution nis b = -1 and b = -7.

Hi, Julie.

There is not enough there to subtract trinomials.Since there is only one parenthesis, the one looks like the number of the problem, not part of the problem. If it is included, you would be multiplying by the one, which would not make any difference. What are the directions?
