Answer 2

$\textbf{Question:}$

choose the answer from the given option:

(a+b) (c+d)

1. ac+ad+bc+bd

2. 2a+3b+4c+5d

3. a+b+c+dd

$\textbf{Answer:}$

For me the correct option is $\textbf{ 1. ac + ad + bc + bd}$

$\textbf{Explanation:}$

Multiply each term in the first parentheses by each term in the second parentheses (FOIL)

$\red{\textbf{(a + b) × (c + d)}}$

$\green{\textbf{ac + ad + bc + bd}}$ ✓
