Just took the quiz

Answer 2

The correct option is A.

Explanation:

The given expression is

`(x^2-3x)(4x^2+2x-9)`

Use distribution property to simplify the given expression.

According to the distributive property.

`a(b+c)=ab+ac`

`(x^2-3x)(4x^2+2x-9)=x^2(4x^2+2x-9)-3x(4x^2+2x-9)`

Therefore the correct option is A.
