W always equal 1 so you do
( 1+ 2 ) ( 1+ 7 ) = then multiple /
2. x. 8. = 16?

If there is no number in between sets of numbers, it’s going to be multiplication.
So (w+2) x (w+7)

w+2, well, evaluates into w+2.
w+7 is w+7.

We’ll use the FOIL method for this.
FOIL stands for:

First
Outer
Inner
Last

So: w * w.
Combine both w’s, and you get $$w^2$$.

Now multiply the outer terms.
w * 7 = 7w.

Then the inner terms. 2 and w.
2 x w = 2w.

So our current numbers are: $$w^2$$, 7w, and 2w.
We can add 7w and 2w together.
7w + 2w = 9w.

Now multiply the last terms.
2 x 7 = 14.

So, this simplifies to $$w^2+9w+14$$
