Answer 2

The correct operator that enters a circle is a subtraction sign.

Given the expressions

$(4x^5-8x) ()(3x^2-8x+9)$

We need to know which sign goes into the bracket that will give a trinomial when simplified.

A trinomial is a function containing 3-terms.

Using the subtraction sign.

$(4x^5-8x) - (3x^2-8x+9)$

Expand

$= 4x^5-8x - 3x^2+8x-9\\= 4x^5-3x^2-8x+8x-9\\=4x^5-3x^2+0-9\\=4x^5-3x^2-9$

Since the resulting term is a trinomial (3 terms), hence the correct operator that enters a circle is a subtraction sign.
