Question 249368
the fact that you have only factored squared numjkbers might have made you think that x^,*x are factors of x^3
2x^3+40x^2+220x
right away you should see that you can factor out 2 and x
so we factor 2x*(x^2+20x+110)
to factor 110 we start
with 2,55
the we see
2,11,5 they are all prime
none of these add up to 20 nor have a difference of 20
so we can't factor all of x^2+20x+110
but we can factor x^2+20x to x(x+20)
