Replacing x = 1/2 we have: 4x  3a = 0
Have 4.1/2  3a = 0
Have 2  3a = 0
Have 3a = 2
Has a = 2/3
Dress a = 2/3 good

Replacing x = 1/2 we have: 4x  3a = 0
<=> 4.1/2  3a = 0
=> 2  3a = 0
=> 3a = 2
=> a = 2/3
Dress a = 2/3 good

Change \(x=\dfrac{1}{2}\) into \(4x3a=0\) , we have:
\(23a=0\)
\(\Rightarrow3a=2\)
\(\Rightarrow a=\dfrac{2}{3}\)
So \(a=\dfrac{2}{3}\)
