Question

Which of the following gives a product of x^3 - 3x ?

Answer 1

Answer:

Option a

Step-by-step explanation:

Lets verify

RHS

$\\ \rm\longmapsto x(x^2-3)$

• Use distributive law
• a(b-c)=ab-bc

$\\ \rm\longmapsto x(x^2)-3x$

$\\ \rm\longmapsto x^3-3x$

$\\ \rm\longmapsto LHS$

Hence verifed

Answer 2

Answer:

$\longmapsto {x}^{3} - 3x$

By taking x common we get,

$\boxed{x( {x}^{2} - 3)} ✓$

• A. x(x² - 3) is the right answer.
• x(x² - 3) gives the product of (x³ - 3x).
