Can someone please help me get the sum difference and product of this problem I am so lost
x^3+ 2x5∶ x^4x^3+ 3x^2 2x+3

Polynomials 
Steve,
Hey, Terrence. As I said before,
what does the ":" mean? If it just separates two polynomials, then if we call them f(x) and g(x),
f+g = x^3 + x^2 + 2x  2
fg = x^3 + 3x^2  2x
f*g = 2x^5  2x^4 + 3x^3  x^2  2x + 1

Steve,
Hmm. different problem, so disregard the above.
sum: x^4+3x^23
diff: x^4 + 2x^3  3x^2 + 4x  8
prod: x^7  x^6 + 5x^5  9x^4 + 14x^3  19x^2 + 16x  15
