3x^2 -24x - 3840
D = (24)^2 - 4*3*3840
D = 256 - 46080
D= - 45824
D<0
so there are no real roots

Hey friend
Here is your answer
=3x²-24x-3840
=3(x²-8x-1280)
=x²-8x-1280
=x²-(40-32)x-1280
=x²-40x+32x-1280
=x(x-40)+32(x-40)
=(x+32)(x-40)
x+32=0
x= -32
x-40=0
x=40
==============================
THE ROOTS OF THE EQUATION ARE -32 AND 40
==============================
HOPE THIS HELPS YOU ☺
