(b+8)(b+2)

Question

its has to be done on a chart

Answer 1

for clarification on the b2...that is b to the power of 2 or b square. b^2

Answer 2

(b + 8 ) (b + 2)

Use the FOIL method - First, Outside, Inside, Last

(a + b) (c + d) = ac + ad + bc + bd

ac is the first term of each

ad is the outside term of each

bc is the inside term of each

bd is the last term of each

For this case

(b + 8 ) (b + 2) = b² + 2b + 8b + 16

Combining like terms gives

(b + 8 ) (b + 2) = b² + 10b + 16
