Question

find the product (10-5m) (4m+9)

Answer 1

Answer:

=> Product : ( 10 - 5m ) ( 4m + 9 )

=> Product : [ 10 ( 4m ) + 10 ( 9 ) - 5m ( 4m ) - 5m ( 9 ) ]

=> Product : [ 40m + 90 - 20m² - 45m ]

=> Product : [ 20m² - 5m + 90 ]

Hence this is the required Product.

Answer 2

$(10-5m)(4m+9)\\\\=10(4m+9)-5m(4m+9)\\\\=40m+90-20m^2-45m\\\\=-5m-20m^2+90\\\\=90-20m^2-5m$

This is the answer

Hope it helped.
