Answer:

The correct option is A.

Explanation:

The given expression is

(4x^2+3x-7)(x-2)

If a ,b, c are three real number, then by distributive property,

$a(b+c)\Leftrightarrow ab+ac$

Using distributive property, then given expression can be written as

(4x^2+3x-7)(x)+(4x^2+3x-7)(-2)

Option A is not a correct way to rewrite the given expression and option C represents a correct way to rewrite the given expression.

Using distributive property, then given expression can be written as

(4x^2)(x-2)+(3x)(x-2)+(-7)(x-2)

Option D represents a correct way to rewrite the given expression.

Again using distributive property in the above expression, we get

(4x^2)(x)+(4x^2)(-2)+(3x)(x)+(3x)(-2)+(-7)(x)+(-7)(-2)

Option B represents a correct way to rewrite the given expression.

Therefore the correct option is A.
