Please help me with this question!!!

I am struggling with this completing square + turning point question

Find the coordinates of y = 2x^2 - 6x + 4
Apparently, the answer for the turning point is (3/2, -1/2) and the completing the square is (x-3/2)^2 - 1/2

However, I got (3/2,-7/4) and (x - 3/2)^2 - 7/4 ??
I tried to search up how bc i keep getting the same answer 😭

After getting to 2( (x-3/2)^2 -9/4)+4 make sure you expand the bracket with the 9/4 so do 9/4 x 2 as it is still inside the bracket when you factorised out the 2. Then you get -9/2 + 4 which is -1/2
