Answer:
x = 1.1 and x = -2.43
Step-by-step explanation:
We have the quadratic equation, i.e.
Now, we know that,
'The quadratic formula to find the solution of 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
i.e. 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.
