Step-by-step explanation:
Here,
the given polynomials are;
(x^2+5x+2)-(5x^2-x-2)
now, when we open bracket of second polynomial we get,
=x^2+5x+2-5x^2+x+2
combining like terms and simplifying them we get;
=x^2-5x^2+5x+x+2+2
=-3x^2+6x+4.
Therefore, the answer is-3x^2+6x+4 or, taking - (minus) commo it will be -(3x2-6x-4).
Hope it helps....
