Compare with standard form

We get,
a=1,b=8,c=14.
Formula for Quadratic Equations is:

Then substituting the values of a,b and c,we get:

Then step by step we get,

Therefore we have 2 values possible for x,which are:
OR

Note that square root of 8 is: 2.828
On further solving as per formula,we get possible values of x as:
(-8+2.828)/2 OR (-8-2.828)/2
Resulting in rounded off values of x as:
-2.586 OR -5.414
Therefore,
Solution Set={-2.586,-5.414}
Hope you followed this,
Best of luck.
