Expand the following algebraic expression (n + 5) (n + 3)

n²+8n+15

Step-by-step explanation:

Given expression is (n+5)(n+3).

We have to expand it.

(n+5)(n+3)

Each of the two terms in first binomial is multiplied by the second binomial.

n(n+3)+5(n+3)

Each of the two terms in first binomial is multiplied by the each term of second binomial.

n(n)+n(3)+5(n)+5(3)

simplify

n²+3n+5n+15

add like terms

n²+n(3+5)+15

n²+n(8)+15

n²+8n+15 which is the answer.

10.4 inches
