The equivalent expression to [tex]2s + (-4s)[/tex] is [tex]-2s.[/tex]
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 [tex]2s + (-4s)[/tex], the common term between [tex]2s[/tex] and [tex]-4s[/tex] is the term s. So we take the term s as the common factor.
So taking s out of [tex]2s + (-4s)[/tex] we get [tex]s (2+(-4)).[/tex]
Step 2:
If we multiply a positive with a negative we get a negative. S0 [tex]+(-4) = -4.[/tex]
[tex]2s + (-4s) = s (2-4) = s(-2) = -2s.[/tex]
So the equivalent expression to [tex]2s + (-4s)[/tex] is [tex]-2s.[/tex]
