Question

Combine like terms to create an equivalent expression 2s+ (-4s) pls help

Answer 1

The equivalent expression to
`2s + (-4s)` is
`-2s.`

Explanation:

Step 1:

In sums like these, it is easier to take the common term out of the simplification.

In the expression
`2s + (-4s)`, the common term between
`2s` and
`-4s` is the term s. So we take the term s as the common factor.

So taking s out of
`2s + (-4s)` we get
`s (2+(-4)).`

Step 2:

If we multiply a positive with a negative we get a negative. S0
`+(-4) = -4.`

`2s + (-4s) = s (2-4) = s(-2) = -2s.`

So the equivalent expression to
`2s + (-4s)` is
`-2s.`
