Question

Write the given polynomial in standard form and write its degree .

y³+2y(y-y³)+5y²+5y+15.
If necessary simplify.
​

Answer 1

In Standard form it is -2y^4 + y^3 + 7y^2 + 5y + 15.

Degree 4.

Explanation:

y³+2y(y-y³)+5y²+5y+15

= y^3 + 2y^2 - 2y^4 + 5y^2 + 5y + 15

= -2y^4 + y^3 + 7y^2 + 5y + 15
