Question

How do you find the product of `((a+4)(a-5))/a^2*(6a)/(a+4)`?

Answer 1

`=> color(purple)((6 (a-5)) / a = 6(1 - 5/a)`

Explanation:

`((a+4)(a-5))/a^2 * (6a) / (a +4)`

`(cancel((a+4))(a-5)) / cancel(a^2)^color(red)(a) * (6cancel(a)) / cancel(a+4)`

`=> color(purple)((6 (a-5)) / a = 6(1 - 5/a)`
