1.	Find each of the following products: (3m – 4n) × (2m – 3n)
Answer» By using horizontal method, We have; = (3m – 4n) × (2m – 3n) = 3m(2m – 3n) – 4n(2m – 3n) = 6m² – 9mn – 8mn + 12n² = 6m² – 17mn + 12n²

Answer»

By using horizontal method,

We have;

= (3m – 4n) × (2m – 3n)

= 3m(2m – 3n) – 4n(2m – 3n)

= 6m² – 9mn – 8mn + 12n²

= 6m² – 17mn + 12n²
