Enter quadratic equation in standard form:
-->  x2 +  x +  


Solution by Convert to Vertex Form and Graph-->  
Step 1: Group the first 2 terms together, separating them from the constant term.
--> 
Step 2: Factor out leading coefficient, for completing the square to work, the coefficient of x2 must be 1.
-->
Step 3: Complete the square, Take half of x coefficient and square it. Notice to keep equation balanced you must add this number and subtract it making the net effect zero.
--> 
--> 
Step 4: Distribute and add constants.
--> 
--> 
Now it is successfully in vertex form and can be easily graphed.
The vertex is at (-3,-4)
The parabola opens up and has a y-intercept at (0, 14)

Dwould be the answer
