Show that (x+1)(x+3)(x+5) can be written in the form ax^3+bx^2+cx+d where a, b and c are all positive integers, and d is a negative integer

Select the correct answer from each drop-down menu. consider the following polynomials equations. 3x^2(x-1) and -3x^3+ 4x^2-2x+1 perform each operation and determine if the result is a polynomial. is the result of a + b a polynomial? yes or no is the result of a - b a polynomial? yes or no is the result of a · b a polynomial? yes or no
