Answer:
Sum of the polynomials is just a matter of combining like terms, with some order of operations.
Given the polynomials : \((-x^2+9)\) and \((-3x^2-11x+4)\)
First arrange the given Polynomial in standard form.
A Standard form of a polynomial means that the term with highest degree is first and each of the following terms
Since the given polynomial are already in standard form i.e,
\(-x^2+9\) and \(-3x^2-11x+4\)
then, the Sum of the polynomials is:
\((-x^2+9)+(-3x^2-11x+4)\)
or
\(-x^2+9-3x^2-11x+4\) [after removing bracket]
Combine like terms:
\(-4x^2+9-11x+4\)
or
\(-4x^2-11x+13\)
Therefore, the sum of polynomials of \((-x^2+9)\) and \((-3x^2-11x+4)\) is; \(-4x^2-11x+13\)
