Question

Subtract these polynomials (3x^3-4x^2+x-2)-(x^3-5x^2+3x+2)

Answer 1

The answer is 2x^3 + x^2 -2x - 4

Answer 2

Answer:  $2x^3+x^2-2x-4$

Step-by-step explanation:

Given the expression:

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

It is important to remember the multiplication of signs:

$(+)(+)=+\\(-)(-)=+\\(+)(-)=-$

Then, knowing this, we can distributive the negative sign:

$=3x^3-4x^2+x-2-x^3+5x^2-3x-2$

The final step is to add the like terms. Then we get:

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