4(v(x+5) +5)^2

Question

perform indicated operations and simplify

Answer 1

Based on your previous problems, I think this problem is 4[√(x + 5) + 5]². Let's work on the inside of the parentheses first.

 

4[(x + 5) + 5√(x + 5) + 5√(x + 5) + 25] by using FOIL to expand the binomial 

 

= 4[(x + 5) + 10√(x + 5) + 25] Combine like-terms to get:

 

4[x + 10√(x + 5) + 30]

 

= 4x + 40√(x + 5) + 120
