you need to find factors of -42 that add up to 19

anonymous · Answer

are you following?

anonymous · Answer

Yes! THis is very helpful

anonymous · Answer

anonymous · Answer

Since -42 is Negative one factor has to be positive and other one be negative REMEMBER this!

anonymous · Answer

2,3,7

anonymous · Answer

Your answer will be written similar to this form ..(x+1) (x+2)

anonymous · Answer

anonymous · Answer

I know the form, i really just get stuck on the factoring

anonymous · Answer

What do you have so far

anonymous · Answer

im stuck on getting the factors of 42 that add up to 19

anonymous · Answer

Do you know what a factor tree or table is?

anonymous · Answer

i have an idea,

anonymous · Answer

Well factor down -42

anonymous · Answer

Have you checked your textbook on methods to solve this? You need to read up on factoring, because i can't just give you the answer. for this polynomial  form ax^2+bx+c

anonymous · Answer

Ok done. I have the factors how do i out them in (x-1)(x+1) format?

anonymous · Answer

2/7 x -3 = -6/7 which is c/a and 2/7-3=-19/7 which is b/a so insert 2/7 as the right hand term of one factor and -3 as the right hand term of the other factor.. (x+2/7)(x-3).... are u getting this?

anonymous · Answer

Do you know how to remove the fraction?

anonymous · Answer

You can do it i promise!

anonymous · Answer

Multiply the first term of the factor by the denominator of the second term.

anonymous · Answer
