Question

1. which expression will result if you use the foil method to multiply $(a + b)(c + d)$?$circ$ $ac + bdLXB0circ$ $ac + ad + bc + bd$$circ$ $ac + 2bc + bd$

Explanation:

Step1: Apply FOIL First Terms

Multiply first terms: $a \times c = ac$

Step2: Apply FOIL Outer Terms

Multiply outer terms: $a \times d = ad$

Step3: Apply FOIL Inner Terms

Multiply inner terms: $b \times c = bc$

Step4: Apply FOIL Last Terms

Multiply last terms: $b \times d = bd$

Step5: Sum all products

Combine the results: $ac + ad + bc + bd$

Answer:

O $ac + ad + bc + bd$
