Answer:

$\Huge\boxed{2x^3+5x^2-7x+20}$

Step-by-step explanation:

$\text{Use FOIL:}\\\\(a+b)(c+d)=ac+ad+bc+bd$

$(x+4)(2x^2-3x+5)\\\\=(x)(2x^2)+(x)(-3x)+(x)(5)+(4)(2x^2)+(4)(-3x)+(4)(5)\\\\=2x^3-3x^2+5x+8x^2-12x+20\\\\\text{combine like terms}\\\\=2x^3+(-3x^2+8x^2)+(5x-12x)+20\\\\=2x^3+5x^2-7x+20$

Which of the following shows that polynomials are closed under subtraction when polynomial 5x − 6 is subtracted from 3x2 − 6x +

Ludmilka [50]

The resulting polynomial when 5x -6 is subtracted from 3x² -6x +2 is; 3x² -11x +8.

<h3>What is the result of the polynomial subtraction?</h3>

It follows from the task content that the polynomial 5x -6 is to be subtracted from 3x² -6x +2.

Hence, the subtraction goes thus; 3x² -6x +2 -(5x-6).

Hence, 3x² -6x +2 -5x+6

= 3x² -11x +8.
