Question 1: Given the polynomials P(x) and Q(x) below, calculate R(x) = P(x) + Q(x).

P(x) = x3 + 3x2 - 1
Q(x) = -2x2 - x + 4









Question 2: Given the polynomials P(x,y) and Q(x,y) below, calculate R(x,y) = P(x,y) - Q(x,y).

P(x,y) = 3x3 + xy2 - xy + 4
Q(x,y) = -2x3 + xy2 - y2 - 5









Question 3: Given the polynomials P(x) and Q(x) below, calculate R(x) = P(x) · Q(x).

P(x) = x2 - x
Q(x) = x - 3

P(x) = x3 + 8x2 - 9x .







Question 6: Given the polynomials P(x,y,z) and Q(x,y,z) and R(x,y,z) below,

P(x,y,z) = (x + y + z)2
Q(x,y,z) = x2 + y2 + z2
R(x,y,z) = xy + yz + zx

which of the following identities is true?







Question 7: What is the third term in the expansion of (x - 2)10
