Question

D) Find the product of the following
1) (2m - 4n) (3m - 8n)

2) 5a(2ab+4bc-3ac)​

Answer 1

Step-by-step explanation:

1)Given that :(2m - 4n) (3m - 8n)

=>(2m)(3m-8n)-4n(3m-8n)

=>(2m×3m)+(2m×-8n)-(4n×3m)+(-4n×-8n)

=>6m²-16mn-12mn+32n²

=>6m²-28mn+32n²

(2m - 4n) (3m - 8n)=6m²-28mn+32n²

-----------------------------------------------------------

2)Given that:5a(2ab+4bc-3ac)

=>(5a×2ab)+(5a×4bc)-(5a×3ac)

=>10a²b+20abc-15a²c

5a(2ab+4bc-3ac)=10a²b+20abc-15a²c
