Question

2x2 − 4x = 0
A.
0, -4
B.
0, -2
C.
0, 2
D.
2, 4

Answer 1

C

Explanation:

We see that we can factor out 2x from the equation! So our equation becomes 2x(x-2) = 0.

Since the only way for things to multiply to equal to zero is if at least one of the numbers is 0.

So if x-2 is the 0, then x = 2.

If 2x is the 0, then x = 0.

So our answer is C. 0,2
