2x3

x= (10) +-√-(-10*) -4x3x(-10)

------------------------------------

2x3

x= (10) +-√-(-10*) -4x3x(-10)

------------------------------------

x= (10) +-√-10 (-10+4x3x10)

------------------------------------

x= (10) +-√-10 (-10-4x3)

------------------------------------

6

x= (10) +-√-10 (-10-12)

------------------------------------

6

x= (10) +-√-10 (-22)
