Question

Simplify: 3m/m-6*5m^3-30m^2/5m^2
A.7
B.m+7
C.m+8
D.3m

Answer 1

I think you meant this: (3m/m-6)*(5m^3-30m^2/5m^2)
If that's the case, the simplified form:
=3m

Answer 2

D.
`3m`

Explanation:

We have been given an expression
`(3m)/(m-6)* (5m^3-30m^2)/(5m^2)`. We are asked to simplify our given expression.

First of all, we will factor our expression as:

`(3m)/(m-6)* (5m^2(m-6))/(5m^2)`

To simplify our given expression, we need to cancel out common factors as shown below:

`(3m)/(1)* (5m^2)/(5m^2)`

`(3m)/(1)* 1`

`3m`

Therefore, the simplified form of our given expression would be
`3m` and option D is the correct choice.
