a couple math problems help please

Evaluate each polynomial -2x4-3x2+5-9 for x=2

Seond math problem

(w2-2w+1)+(2w-5+w2)

2. #1) $\displaystyle f(x)=-2x^4-3x^2+5-9$

This is the same as $\displaystyle f(x)=-2x^4-3x^2-4$

So $\displaystyle f(2)=-2*(2^4)-3*(2^2)-4=-32-12-4=?$

#2)$\displaystyle (w^2-2w+1)+(2w-5+w^2)$

Group it like this $\displaystyle (w^2+w^2)+(2w-2w)+(5-1)$
