Answer:
[tex]2s+\left(-4s\right)=-2s[/tex] is the equivalent expression as [tex]2s+\left(-4s\right)[/tex] is equal to [tex]-2s[/tex].
Step-by-step explanation:
Considering the expression
[tex]2s+\left(-4s\right)[/tex]
As we know that
- Like terms are said to be the terms which hold the same variables raised to the same power.
- For example, [tex]3x[/tex] and [tex]2x[/tex] are like terms as they contain the same variable [tex]x[/tex] raised to the same power.
Lets solve the expression
[tex]2s+\left(-4s\right)[/tex]
[tex]\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a[/tex]
[tex]2s-4s[/tex]
[tex]\mathrm{Add\:similar\:terms:}\:2s-4s=-2s[/tex]
[tex]-2s[/tex]
Therefore,
[tex]2s+\left(-4s\right)=-2s[/tex] is the equivalent expression as [tex]2s+\left(-4s\right)[/tex] is equal to [tex]-2s[/tex].
