HELP: Factor x² + 4x - 4 ?
Factor out =)
Update:The middle term should be the sum of both the numbers right
-2 + 2 = 0 not 4
is it really (x-2) (x+2)? ._.

-(-2+2 sqrt(2)-x) (2+2 sqrt(2)+x)
(x-2)(x+2) the one above me isnt right because -4 does not have a x in it. if you distribute what she said you get a -4x at the end.
x = -2 + 2 root(2) and -2 -2root(2)
