Heya
_______________________________
x - 2 - x = 3x² - 6x
=>
3x² - 6x + 2 = 0
The above quadratic equations have two roots Viz m And n
x = m OR x = n
=>
3m² - 6m + 2 = 0
=>
m =( 6+- 2√3 )/6
=>
m = ( 3 +- √3 ) / 3
And
3n² -6n + 2 = 0
=>
n = (6 +- 2√3 ) /6
=>
n = (3 +- √3 ) /3
So,
m × n = {( 3 + √3 ) /3}× {( 3 + √3 )/3}
=>
m × n = ( 3 + √3 )²/9
=>
m × n =( 9 + 3 + 6√3 )/9
=>
m × n = (2/3)( 2 + √3 )
OR
m × n =(2/3) ( 2 - √3 )
