Sense you do not have any options, this may be quite harder, But, I believe I got this. So, by looking at the following, it would look like the expression below:
[tex] \boxed{x^2 + 9x + 8 }[/tex]
We cant not use the numbers that are above to would give us 8. 2+9 would not equal 8 which would then show us that your answer may be the following:
Your answer: [tex]\boxed{\boxed{\bf{ (x + 1)(x + 8) }}}[/tex]
