I think it could be false? Because I think there are other ways. But since it is in absolute value. It would equal to 2. Whether it is -2 or 2.
OpenStudy (rz172):
and because the answer could be x= -2
OpenStudy (mathstudent55):
The answer choices are only true or false?
There is no option of sometimes?
OpenStudy (rz172):
It's just true and false.
OpenStudy (rz172):

I think it is true.
I am sure 90%.
What do you think?
OpenStudy (mathstudent55):
x^2 - 5x + 6 = 0 iff x = 2 is false bec x can also equal 3.
OpenStudy (3mar):
He talks about x=2, not x=-2
OpenStudy (mathstudent55):
BTW, iff = if and only if
OpenStudy (3mar):
mathstudent55 is right!
Sorry for that mistake!
