@TheSmartOne Again failing with factoring.. Halp

Answer 1

\[x^2+x-1\] Is there a factor of this?

Answer 2

I tried to solve it and I couldnt find a factor by any way.

Answer 3

yep right
you need product of AC= which is -1
and middle number is = 1

Answer 4

factor of 1 is just 1 times 1
but 1+1 =2 or 1-1 =0
which isn't the middle number so the answer is ?
