Answer:
The equation of parabola in vertex form is 
Step-by-step explanation:
Given coordinate of vertex is
and the parabola passes through the point 
So, the equation of parabola in vertex form is

Where
is the coordinate of the vertex.

Plugging these value in equation we get,

Now, we will find the value of 
Plug the coordinate 


Plug the value of
in the equation 
So, the equation of parabola with vertex
and passes through the point
is
≅
Answer:
2x = -5 +/- root 5 (opt 3)
Step-by-step explanation:
0 = 4f(x)
= 4(x^2 + 5x + 5)
= 4x^2 + 20x + 20
= (2x)^2 + 2*2x+5 + 25 - 5
= (2x + 5)^2 - (root 5)^2
= ((2x+5) - 5) ((2x + 5) + 5)
= (2x + 5 - 5) (2x + 5 - 5)
Therefore, 2x = -5 +/- root 5
