Answer 1

Answer:

$\Large\boxed{\mathsf{a^2+8a+15}}}}$

Step-by-step explanation:

QUESTION:

(a+3) (a+5)

TO FIND:

The product of (a+3) (a+5).

TO SOLVE:

With FOIL method.

Expand the expression form.

SOLUTIONS:

First, use FOIL method formula.

FOIL METHOD FORMULA:

$\displaystyle \mathsf{(A+B)(C+D)=AC+AD+BC+BD}}$

A=A

B=3

C=A

D=5

$\displaystyle \mathsf{AA+A*5+3A+3*5}}}$

$\displaystyle \mathsf{AA+5A+3A+3}}$

Solve.

Add similar elements. (Add the numbers from left to right.)

$\displaystyle \mathsf{5+3=8}$

$\displaystyle \mathsf{A^2=AA}$

$\displaystyle \mathsf{5\times3=15}$

$\Large\boxed{\mathsf{\Rightarrow a^2+8a+15}}$

In conclusion, the correct answer is a²+8a+15.
