Question

10. Expand and Simplify (r+3) (r+11)=

Answer 1

Answer:

r^2 + 14r + 33

Step-by-step explanation:

Apply the "FOIL" method for multiplying two binomials:

(r+3) (r+11) = r^2 (first terms) +

                    + 33 (last terms) +

                     + 11r (outer terms) +

                      + 3r (inner terms)

Combining ilke terms, we get:

r^2 + 14r + 33
