Hi, so I posted my questions but they didn't get answered yesterday, and I would really like some help with them, so I am going to repost them. :)
1. Let f(x)=x+5 and let g(x)=x^2+1. Let p(x)=g(x)+f(x) and let q(x)=g(x)-f(x). Find p(x) * q(x).
2. Consider the polynomials f(x)=4x^3+3x^2+2x+1 and g(x)=3-4x+5x^2-6x^3. Find c such that the polynomial f(x)+cg(x) has degree 2.
