anonymous · Answer

I think this is the correct answer:

(x^2+7)(x^3-5x+4)

(x^5-5x^3+4x^2+7x^3-35x+28

x^5+2x^3+4x^2-35x+28

so do you think it is right or do you know. and is the last line the final answer

anonymous · Answer

I prefer tentative answers, that is just me, but that is what I would put if I were taking the said test/worksheet. Yes, the last line is the final answer.

anonymous · Answer

okay well thank you thank you much! i would have got this wrong because i would have used the foil method

anonymous · Answer

When you want to separate an algebraic problem into a binomial.
