factored form: "A factored form is a parenthesized algebraic expression. In effect a factored form is a product of sums of products … or a sum of products of sums … Any logic function can be represented by a factored form, and any factored form is a representation of some logic function"


just in case if you didn't know the definition,

okay so we have:
f(x) = 9x^3 + 2x^2 - 5x + 4 
 g(x) = 5x^3 - 7x + 4.

add the functions together:
f(x)-g(x) = [9x^3+2x^2-5x+4] - [5x^3-7x+4]

 what do you get?

4x^3 + 2x^2 + 2x?

@ThereisnoUsername is that correct?

thereisnousername · Answer

yes i believe so

anonymousasker · Answer

@ThereisnoUsername is that the answer in factored form as well or would that be something different?
