Answer:

$2x^{2} + 6x - 4$

Step-by-step explanation:

$(3x^{2} + x - 3) - (x^{2} - 5x + 1) \\ 3x^{2} + x - 3 - x^{2} + 5x - 1 \\ combine\: like \: terms \\ 2x^{2} + 6x - 4$

Subtract each term of g(x) from each corresponding term of f(x)

3x^2 - x^2 = 2x^2

X—5x = x +5x = 6x

-3 -1 =-4

Now combine them to get final answer:

2x^2 + 6x -4

(A) Product of $-2x^{3}+x-5$ and $x^{3}-3x-4$ is:

$(-2x^{3}+x-5)(x^{3}-3x-4)$

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

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

$=-2x^{6}+6x^{4}+8x^{3}+x^{4}-3x^{2}-4x-5x^{3}+15x+20$

$=-2x^{6}+6x^{4}+x^{4}+ 8x^{3}-5x^{3}-3x^{2}-4x+15x+20$

$=-2x^{6}+7x^{4}+3x^{3}-3x^{2}+11x+20$

(B) Yes.

Product of $-2x^{3}+x-5$ and $x^{3}-3x-4$ = Product of $x^{3}-3x-4$ and $-2x^{3}+x-5$ because multiplication is commutative.

Commutative Property of multiplication says that a.b = b.a.

Thus, multiplication is same irrespective of the order of two numbers.
