Answer:
Option a
Step-by-step explanation:
Lets verify
RHS
[tex]\\ \rm\longmapsto x(x^2-3)[/tex]
[tex]\\ \rm\longmapsto x(x^2)-3x[/tex]
[tex]\\ \rm\longmapsto x^3-3x[/tex]
[tex]\\ \rm\longmapsto LHS[/tex]
Hence verifed
Answer:
[tex] \longmapsto {x}^{3} - 3x \\[/tex]
By taking x common we get,
[tex] \boxed{x( {x}^{2} - 3)} ✓\\ [/tex]
