Which is not a correct way to rewrite this expression using the distributive property?
[tex]\[
(2x^2 + 4x - 7)(x - 2)
\][/tex]

A. [tex]\((2x^2)(x) + (2x^2)(-2) + (4x)(x) + (4x)(-2) + (-7)(x) + (-7)(-2)\)[/tex]

B. [tex]\((2x^2 + 4x - 7)(x) + (2x^2 + 4x - 7)(-2)\)[/tex]

C. [tex]\((2x^2)(x - 2) + (4x)(x - 2) + (-7)(x - 2)\)[/tex]

D. [tex]\((2x^2 + 4 - 7)(x) + (2x^2 + 4x - 7)(x - 2)\)[/tex]

Sagot :

To determine which option is not a correct way to rewrite the expression [tex]\(\left(2 x^2 + 4 x - 7 \right)(x - 2)\)[/tex] using the distributive property, let's closely examine each option step-by-step:

A. [tex]\(\left(2 x^2\right)(x) + \left(2 x^2\right)(-2) + (4 x)(x) + (4 x)(-2) + (-7)(x) + (-7)(-2)\)[/tex]

This option is correctly using the distributive property by distributing each term of [tex]\(\left(2 x^2 + 4 x - 7 \right)\)[/tex] to both [tex]\(x\)[/tex] and [tex]\(-2\)[/tex]. Thus, Option A is a correct rewriting.

B. [tex]\(\left(2 x^2 + 4 x - 7 \right)(x) + \left(2 x^2 + 4 x - 7 \right)(-2)\)[/tex]

This correctly shows the distribution of the entire polynomial [tex]\( \left(2 x^2 + 4 x - 7 \right) \)[/tex] to both [tex]\(x\)[/tex] and [tex]\(-2\)[/tex]. Thus, Option B is a correct rewriting.

C. [tex]\(\left(2 x^2\right)(x - 2) + (4 x)(x - 2) + (-7)(x - 2)\)[/tex]

This option is grouping [tex]\(\left(2 x^2 + 4 x - 7 \right)\)[/tex] and then distributing [tex]\(x - 2\)[/tex]. Hence, Option C is a correct rewriting.

D. [tex]\(\left(2 x^2 + 4 - 7 \right)(x) + \left(2 x^2 + 4 x - 7 \right)(x - 2)\)[/tex]

Notice in Option D, there is an error within the expression inside the parentheses. It should be [tex]\(\left(2 x^2 + 4 x - 7 \right)\)[/tex], but instead it is written as [tex]\(\left(2 x^2 + 4 - 7 \right)\)[/tex], which simplifies incorrectly. Therefore, Option D is not a correct rewriting.

So, the incorrect way to rewrite the expression using the distributive property is:

Option D. [tex]\(\left(2 x^2 + 4 - 7 \right)(x) + \left(2 x^2 + 4 x - 7 \right)(x - 2)\)[/tex]
