Question

factor 49x^3-35x^2+56x-40

Answer 1

what class is this for?

Answer 2

this is for my pre calculus class but my teacher felt it was important to know how to factor

Answer 3

well we have to find a single root to begin. Do you know how to do this?

Answer 4

We start with the fundamental theorem of algebra, which states that the number of roots is equal to the largest polynomial number (in this case 3) So we are looking for 3 roots

Answer 5

No, I forgot all about factoring, the last time I did it was when I was in 7th grade, so about 4 years ago

Answer 6

Well, let's try this, try to identify something that can be factored out of the first two terms

Answer 7

then repeat this for the last two terms
