Answer 2

Given :

An expression $24x^{2} (3-5x)$

To find:

The value of the given expression when x is 3.

Step-by-step explanation:

• The product of the expression can be found by following these steps.
• The given expression is

       $24x^{2} (3-5x)$

• Take the number inside.

       $24(3)x^{2} -(5)(2)(x)(x^{2} )$

• Remove the brackets

       $72x^{2} -10x^{3}$

• Substitute the value of x in the expression.

       $72(3)^{2} -10(3)^{3}$

• Square the values

       $72(9)-10(27)$

• Remove the brackets

       $648-270$

• Subtract the value

       $378$

       

Final answer :

The value of the expression $24x^{2} (3-5x)$ is $378$.
