Question 1196808
This is not the full solution.


{{{3(x^2+5x+10+(5/2)^2-(5/2)^2)}}}

{{{3(x^2+5x+(5/2)^2+10-(5/2)^2)}}}

{{{3((x+5/2)^2+40/4-25/4)}}}
{{{3((x+5/2)^2+15/4)}}}

{{{3(x+5/2)^2+45/4}}}
{{{y=3(x+5/2)^2+11&1/4}}}-----------you can read the vertex and solve for the roots.


{{{-(x^2-4x+8)}}}
{{{-(x^2-4x+4-4+8)}}}
{{{-((x-2)^2+4)}}}
{{{y=-(x-2)^2-4}}}--------------you can read the vertex and solve for the roots.
