Answer:
x = 1.1 and x = -2.43
Step-by-step explanation:
We have the quadratic equation,  i.e.
 i.e.  
 
Now, we know that,
'The quadratic formula to find the solution of  is given by
is given by  .
.
On comparing, we get from the given equation,
a= 3, b= 4 and c= -8
Substituting these values in the given quadratic formula, we get,
 .
.
i.e.  .
.
i.e. 
i.e. 
i.e.  and
 and 
i.e.  and
 and 
i.e. x = 1.1 and x = -2.43
Thus, the solution of the quadratic equation  using the quadratic formula is x = 1.1 and x = -2.43.
 using the quadratic formula is x = 1.1 and x = -2.43.
