8√3. 8√3
3 / 4√3. , -2 / √3
let roots be alpha, beta
alpha+beta = -b/a
from eq. -5 / 4√3
3 /4√3 + (-2 / √3)
3 - 8 / 4√3. = -5/4√3
alpha x beta from eq. - 1/2
3/4√3 x -2/√3
-6/12 = -1/2

➡➡Here is your answer ✔✔✔
➡Soln--
f(x)= 4√3x^2+5x-2√3
➡ 4√3x2 + 5x - 2√3 = 0
➡ 4√3x2 + 8x - 3x - 2√3 = 0
➡ 4x(√3x + 2) - √3(√3x + 2)
➡ (4x - √3)(√3x + 2)
➡ x = √3 / 4 , x= - 2/√3
