First, distribute the terms.

1(2x^3) = 2x^3

-1(x^2+11) = -x^2-11

Standard form:

2x^3 - x^2 - 11

Since there is a 3, the degree of polynomial is cubic.

To find out if the triangle is a right triangle, we must check if the following equation is true:

$(15)^2+(20)^2=(25)^2^{}^{}^{}$

on the left side, we have:

$(15)^2+(20)^2=225+400=625^{}$

and on the right side, we have:

$(25)^2=625$

since on both sides we get 625, we have that the brace forms a right triangle.
