3x^2 -24x - 3840

D = (24)^2 - 4*3*3840

D = 256 - 46080

D= - 45824

D<0

so there are no real roots

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 ☺
