Your answer should be a polynomial in standard form.

 

(5 + w)(w + 4) = ?

to expand this polynomial, we should multiply the factors in order from left to right. hopefully you can follow this process - 

 

5w + 5*4 + w^2 + 4w.

 

to simplify, we combine the like terms, to get:

 

w^2 + 9w + 20

 

hope this helped! sorry if this wasn't too clear. 

 

here are a few websites that may help you understand this better:

also try out Symbolab's expansion calculator. it provides a step-by-step expansion of polynomial expressions as well.

 

if you have some time, give these a try! Google searches are also useful to help you learn more too! laugh
