Answer:
Step-by-step explanation:
4x² + 4√3x + 3 can be compared to general form ax² + bx + c
on comparing, a=4 ,
b=4√3 and
c= 3
quadratic formula: x = ( -b ±√b²-4ac )/ 2a
on putting values of a, b, c ,
x = ( -4√3 ± √48 - 4(4)(3) ) / 2×4
x = - 4√3/8
x = - √3/2

GIVEN :-
TO FIND :-
- Roots of the equation by quadratic formula.
TO KNOW :-
Here ,
- a → Coefficient of x².
- b → Coefficient of x.
- c → constant.
SOLUTION :-
We have ,
Here ,
- a = 4
- b = 4√3
- c = 3
Putting values in formula ,
Discriminant is 0 . Hence , roots are equal.
Hence , roots are -√3/2 , -√3/2.
