Question

Simplify the following expressions-4(-1-10n)-(n-2)

Answer 1

According to the given data we have the following expression:

-4(-1-10n)-(n-2)​

So, to simplify the following expression we would make the following steps:

1. We would have to expand -4(-1-10n) by applying the distributive law

distributive law

`a\mleft(b-c\mright)=ab-ac`

Hence, -4(-1-10n)=4 + 40n

So, 4 + 40n -(n-2)​

Then:

With -(n-2)​ we would have to distribute parentheses.

`=-\mleft(n\mright)-\mleft(-2\mright)`
`=-n+2`

So, finally we would have to simplify 4 + 40n - n+2

We would have to add similar elements and similar numbers, so the simplified expression would be:

6 + 39n
