Answer 38

one of yal are wrong .. i dont wanna get the wrong answer @TrojanPoem @MIles3636

Answer 39

Hes Wrong I did My math

Answer 40

@MIles3636 , None of us is wrong, you see the zero as one
3x^2 = 0

Answer 41

@myalina ,it's 3x^2 = 1 or zero ?

Answer 42

1/4x^2 - 4 = 0

A) X = +/-3
B) X = +/-4
C) X = +/-2
D) no solution @MIles3636

Answer 43

it says 0 @TrojanPoem

Answer 44

So the answer is C, he has just seen the zero as one which resulted in miscalculating.
