Answer 1

Answer:

$-20x^3+0x^2+15x-20$

Explanation:

Step 1. To find the first row of the multiplication, we need to multiply -5 by the first expression:

$4x^3+0x^2-3x+4$

The multiplication we have to make is:

$(-5)(4x^3+0x^2-3x+4)$

Step 2. Multiply -5 by all of the terms in the expression:

$=(-5)(4x^3)+(-5)(0x^2)+(-5)(-3x)+(-5)(4)$

Solving the operations:

$-20x^3+0x^2+15x-20$

This is the first row of the multiplication and is shown in the fourth option.

Answer:

$-20x^3+0x^2+15x-20$
