Question

Find the product
(4\m+m)(4/m-m)
​

Answer 1

(16-m^4)/m^2

Explanation:

=(
`(4)/(m)`+m)(
`(4)/(m)`-m)

=
`(4+m^2)/(m)`*
`(4-m^2)/(m)` (LCM)

`(16-m^4)/(m^2)` (a-b)(a+b)

Answer 2

`\\ \sf\longmapsto (4)/(m+m)* (4)/(m-m)`

`\\ \sf\longmapsto (4* 4)/((m+m)(m-m))`

`\boxed{\sf (a-b)(a+b)=a^2-b^2}`

`\\ \sf\longmapsto (16)/(m^2-m^2)`

`\\ \sf\longmapsto (16)/(0)`

`\\ \sf\longmapsto \infty`
