Question
Find the solutions for the equation 
using vertex form.
Hint:
In this question, we have to find the solutions for the equation using vertex form. Vertex form is another form of a quadratic equation. The standard form of a quadratic equation is a
+ bx + c. The vertex form of a quadratic equation is a 
+ k where a is a constant that tells us whether the parabola opens upwards or downwards, and (h, k) is the location of the vertex of the parabola.
The correct answer is:
Given quadratic equation,
Now we isolate constants to the other side,
Adding 4 on both sides, we get
The vertex form of the quadratic equation is 
.

The coordinates of the vertex of the parabola, whose equation is y = 2x2 + 4x - 5 are:
The other method to find the vertex of a parabola is as We know that the x-coordinate of a vertex, (i.e) h is -b/2a. Now, substitute the x-coordinate value in the given standard form of the parabola equation y=ax2+bx+c, we will get the y-coordinate of a vertex.
