Answer:

The new expression is
p' = 5\cdot x^(2)+11\cdot x^(4)-9\cdot x^(15)+14\cdot x^(19)+12\cdot x^(22).

Explanation:

A polynomial is a sum of algebraic monomials such that:


p = \Sigma_(i=0)^(n) c_(i)\cdot x^(i)

Where
n is the degree of the polynomial and
c_(i) is the i-th coefficient of the polynomial. A 22nd degree polynomial has
n = 22, so that given polynomial must added by a monomial with grade 22. Thus:

If
p = 5\cdot x^(2) + 11\cdot x^(4)-9\cdot x^(15)+14\cdot x^(19) and
q = 12\cdot x^(22), then we have:


p' = p+q


p' = 5\cdot x^(2)+11\cdot x^(4)-9\cdot x^(15)+14\cdot x^(19)+12\cdot x^(22)

The new expression is
p' = 5\cdot x^(2)+11\cdot x^(4)-9\cdot x^(15)+14\cdot x^(19)+12\cdot x^(22).
