Find the product of [tex]2x^4\left(2x^2 + 3x + 4\right)[/tex].

A. [tex]2x^8 + 3x^4 + 4x^4[/tex]

B. [tex]4x^6 + 6x^5 + 8x[/tex]

C. [tex]4x^4 + 3x^5 + 2x^6[/tex]

D. [tex]3x^6 + 4x^5 + 5x^4[/tex]



Answer :

To find the product of [tex]\(2 x^4 (2 x^2 + 3 x + 4)\)[/tex], we will expand the expression step-by-step.

1. Distribute [tex]\(2 x^4\)[/tex] to each term inside the parentheses:

[tex]\[ 2 x^4 (2 x^2 + 3 x + 4) \][/tex]

2. Multiply [tex]\(2 x^4\)[/tex] by each term in [tex]\(2 x^2 + 3 x + 4\)[/tex]:

[tex]\[ 2 x^4 \cdot 2 x^2 + 2 x^4 \cdot 3 x + 2 x^4 \cdot 4 \][/tex]

3. Perform each multiplication:

[tex]\[ 2 x^4 \cdot 2 x^2 = 4 x^6 \][/tex]

[tex]\[ 2 x^4 \cdot 3 x = 6 x^5 \][/tex]

[tex]\[ 2 x^4 \cdot 4 = 8 x^4 \][/tex]

4. Combine all the terms obtained:

[tex]\[ 4 x^6 + 6 x^5 + 8 x^4 \][/tex]

Thus, the expanded expression is:

[tex]\[ 4 x^6 + 6 x^5 + 8 x^4 \][/tex]

By comparing this result with the given choices, we see that the correct answer is:

[tex]\[ 4 x^6 + 6 x^5 + 8 x^4 \][/tex]

Therefore, the correct choice is:
[tex]\[ 4 x^6 + 6 x^5 + 8 x^4 \][/tex]
