Question

Write the expression in complete factored form. x2(a + 5) + (a + 5) =

Answer 1

I have no idea what the x is doing, so imma take it out.

First we multiply 2 x a and 2 x 5.

Because we can't directly multiply a variable, we will write 2a.

2a+10+(a+5).

We can remove the parenthesis now.

2a+10+a+5.

Now we add. a has an invisible 1, so we make the 1 visible.

2a+1a+15

3a+15

That's all we can do with the problem.
