Use a direct proof to show that if x +y is even, then 2²y - y³ + 2 is even. Clearly state your reasoning for all statements and use a two-column proof for the body whenever possible. You should include an intro, body (in two column format), and a conclusion. (Hint: It might be beneficial to factor r²y-y³ in your scratch work)
