Factor: (m+n) - 5(m+n)?

Question

My Algebra homework says to factor the above problem and I don't remember how.

Does anyone know how to do this or a website that explains how?

Answer 1

(m+n) - 5(m+n)

= (m + n) ( 1 - 5 )

= - 4 (m + n)

Answer 2

take out gcf of (m+n)

(m+n)(1-5) which is the same as

-4(m+n)

Answer 3

m+n-5m+5n

6n+6m= ugjhhhhh DONT KNOW!

so lost  

Answer 4

(m+n) - 5(m+n)

= (m+n) - 5(m)-5(n)

= m+n-5m-5n

= -4m-4n

= -4(m+n)

search google for a website...

Answer 5

First distribute the -5

(m+n) + (-5m-5n)

Then, since you only have + and -, you can remover the parentheses.

m+n-5m-5n

Combine like terms.

-4m-4n

then you can factor out the -4

-4(m+n)

Answer 6

(m+n)(1 - 5)

(m+n)(-4)

-4(m+n)

When expanded, it becomes -4m - 4n

but the answer on the 3rd line is the most factored.
