Question 594455: How do you factor: v^2 - 2v + 48
Can you answer in 8th grade terms please? I've tried notes, friends, parents, teachers and all over the internet.
Thank you in advance,

---------------
That can't be factored.
Maybe that's why you're having difficulty.
-------------
You can factor v^2 - 2v - 48, but not +48.

You can put this solution on YOUR website! i am gonna give you a little background about factorization.
let's say you have a function x^2+ax+ b, its factorization is (x- c)(x-d), where c*d = 48, and c+d = -a.
with that in mind, we have to find two numbers ( if they exist) whose product is 48 and their sum is 2.
(1, 48) (2, 24) (3, 16) (4, 12) (6, 8) are the only pair of integers whose product of its element is 48; but none of those pair has elements whose sum is 2 , thus that function is not factorisable.
From an 8th grade approach it is not factorisable.
however, that function IS factorisable with complex numbers.
