SOLUTION: I am having a problem finding the product of this equation. I am using the product function(f*g)(x) f(x)=(x+6), g(x)=x^2-2x+12. After multiplying, I end up with x^3-2x^2+12x+6x^2-1

Question 1001247: I am having a problem finding the product of this equation. I am using the product function(f*g)(x) f(x)=(x+6), g(x)=x^2-2x+12. After multiplying, I end up with x^3-2x^2+12x+6x^2-12x+72. When I combine like terms, I get x^3-4x^2+72. I was thinking this was my answer but the answer key has the answer as x^2-2x+18. Did I do something wrong? Can you help me?

Yes, Virginia, there is no Santa Claus. But textbook authors/publishers and teachers/professors/instructors DO make mistakes. Your answer is correct; the answer key is wrong.
