Given s(z)=11+2z^(2) and w(z)=3z^(2)-11z+2, find (s+w)(z).

Question

Given s(z)=11+2z^(2) and w(z)=3z^(2)-11z+2, find (s+w)(z).

(s+w)(z)=

Answer 1

Here, (s+w)(z) can be rewritten as s(z) + w(z). So to solve the problem, simply add the two functions together.

(s+w)(z) = s(z) + w(z) = 11+2z² + 3z² - 11z + 2 = 13 + 5z² - 11z
