Question

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

Answer 1

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

Step-by-step 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 $-2s.$
