(x2 + 13x + 40) ÷ (x + 8)
OpenStudy (espex):
Factor your numerator and you will find that you have terms that will cancel.
OpenStudy (anonymous):
idk how to do it.
OpenStudy (espex):
\(x^{2}+13x+40\) What two things must multiply together to get the first term of \(x^2\)? Place them at the first thing inside the parenthesis ( )( )

(x+8)(x+5)?
OpenStudy (espex):
Very good, now do you see a common factor in the numerator and denominator?
OpenStudy (anonymous):
Nooo ? Im not Sure . X ?
OpenStudy (espex):
The expression held within the ( ) can be treated as if it were a single term.
OpenStudy (espex):
So if you have \(\frac{2*3}{2}\) it would be treated the same as \(\frac{x+8)*(x+5)}{(x+8)}\)

so x+8 is the common factor ?
OpenStudy (espex):
Exactly, and what is anything over itself?\[\frac{1}{1}~or~\frac{2}{2}~or~\frac{(x+8)}{(x+8)}\]
OpenStudy (anonymous):
1
OpenStudy (espex):
Perfect! So your final answer is 1*(x+5)

Thankyou very Much (;
