Answer 2

Answer:

Step-by-step explanation:

There are two solutions. 2x=0 or 4x-3=0.

 

Therefore x=0 or 4x=3.

 

Solution 1)x=0.

 

Solution 2)x=3/4

2x(4x - 3) = 0

 

so, either

 

2x = 0 or 4x - 3 = 0

 

for 2x = 0,  x = 0

 

for 4x - 3 = 0  ---> 4x = 3 ---> x = 3/4

 

so, x = 0 or x = 3/4
