Complete the square to find the turning points, also known as the vertex.
y=2x²+6x+4
y=2(x²+3x+2)
y=2[(x+3/2)²?9/3+2]
y=2(x+3/2)²?1/2
Notice here that you have to multiply BOTH terms by 2, as 2 was the common factor which you took out of the entire expression!
Therefore, the turning points can be picked up such that
x=?3/2,y=?1/2
Therefore coordinates:
(?3/2,?1/2)
