If f(x) and g(x) are two polynomials, which of the following may NOT be a polynomial? A. f(x) + g(x) B. f(x) - g(x) C. f(x) × g(x) D. f(x)/g(x)
What is D

P = 3x^2 + xy - 5y^2, Q = 2x^2 - xy + 3y^2 and R = -6x^2 + 4xy - 7y^2 What is P - (Q + R) ?
What is 7x^2 - 2xy - y^2 Q + R = (2x^2 - xy + 3y^2) + (-6x^2 + 4xy - 7y^2) = 2x^2 - xy + 3y^2 - 6x^2 + 4xy - 7y^2 = -4x^2 + 3xy - 4y^2 So P - (Q + R) = 3x^2 + xy - 5y^2 - (-4x^2 + 3xy - 4y^2) = 3x^2 + xy - 5y^2 + 4x^2 - 3xy + 4y^2 = 7x^2 - 2xy - y^2
