Answer:

f(x)=4√3x^2+5x-2√3

*product=4√3*-2√3=-24

*sum=5x

SPLITTING THE MIDDLE TERM:

4√3x^2+8x-3x-2√3

4x(√3x-2)+√3(√3x-2)

(4x+√3)(√3x-2)

therefore the zeroes are,

-√3/4 and 2/√3

let alpha=-√3/4 and beta=2/√3,

we know,

alpha + beta=-b/a                  and             alpha*beta=c/a

ie,-√3/4+2/√3=-5/4√3                              -√3/4*2/√3=-2√3/4√3

   -3+8/4√3=-5/4√3                                    -2/4=-1/2

-5/4√3=-5/4√3                                             -1/2=-1/2
