Question

How do you work out this problem?
3x3 + 2x2 + 3x+2
I showed three different people my work an they said I did it wrong I am so confuse.

Answer 1

hard to say what's wrong, since you don't say what you're trying to do.

factor it? Rearrange things a bit:

3x^3 + 3x + 2x^2 + 2
3x(x^2+1) + 2(x^2+1)
(3x+2)(x^2+1)

Answer 2

If the cost of a cell phone has decreased 400% during the past 10 years, does that correspond to a cost decrease of four times? Explain your answer as though you were talking to someone who has never taken algebra.

Answer 3

(3x^2y^3)^3
