anonymous · Answer

they are asking if you can factor it using whole numbers

anonymous · Answer

since the $2x\times 2=4$ and $1\times 4=4$ you can try $$(x+2)(x+2)$$ or $$(x+1)(x+4)$$ and see if either give you $x^2+2x+4$

anonymous · Answer

i think that you will find that neither do

arbyj · Answer

i did (x+2) (x+2) at first without realizing 2x2 or 2+2 doesnt equal 2

anonymous · Answer

Are you trying to factor it?

arbyj · Answer

yes

anonymous · Answer

i'm not seeing a way to factor it with whole numbers

anonymous · Answer

You got the x right :P but you'd also want to find the gcf of 4

anonymous · Answer

In this case 2 and 2

anonymous · Answer

(x+2)(x+2) doesn't equal x^2+2x+4 it equals x^2+4x+4

arbyj · Answer

which means its prime, right?

anonymous · Answer

True.

anonymous · Answer

Well its not prime

anonymous · Answer

But i dont think it can be solved

anonymous · Answer

it just can't be factored with whole number integers

It can be solved using a different method (such as the Quadratic Formula but you can't solve it easily by factoring).
