3x^2 - x - 10 = 0
3x^2 - [ 6 - 5 ] x - 10 = 0
3x^2 - 6x + 5x - 10 = 0
3x [ x - 2 ] + 5 [ x - 2 ]
( 3x + 5) ( x - 2)
3x + 5. x - 2
x = -5/3 x = 2
hope this helps ☺☺
3x^2 - [ 6 - 5 ] x - 10 = 0
3x^2 - 6x + 5x - 10 = 0
3x [ x - 2 ] + 5 [ x - 2 ]
( 3x + 5) ( x - 2)
3x + 5. x - 2
x = -5/3 x = 2
hope this helps ☺☺
