Answer:
(-1,0)
Step-by-step explanation:
To find the x value of the vertex use the equation
-b/(2a)
-4/(2*2)= -1
this means that the x coordinate is -1
Now that we know the x value we need to find the corresponding y value
to do this we just plug in x into the equation
2(-1)²+4(-1)+2
2-4+2=0
put it all together and get (-1,0)
