Answer 1

6-x-x²

=> -1(-6 + x + x²)

=> -(x² + x - 6)

=> -(x² + {3 - 2}x -6)

=> -(x² + 3x - 2x -6)

=> -(x{x+3} -2{x +3})

=> -(x +3)(x-2)

I hope this will help you

Answer 2

Heya!

Here is yr answer
_____________________________

=> 6 - x - x²

=> - (-6 + x - x² )

Method l:

We need to change the positions of the Values----(quadratic equation rule)

=> - (x² + x -6)

=> - (x² + 3x -2x -6)

=> - [ x (x+3) -2 (x+3) ]

=> - (x+3) (x-2)

x = -3 ------ x = 2

Method ll:

=> - (x² + x -6)

=> - (x² + 3x -2x -6)

=> - [ x² + (3-2)x -6 ]

=> - [ x² + (3+ (-2) )x + (3) (-2) ]

It is in the form of -------

x² + (a+b)x + ab = (x+a) (x+b)

x = x, a =3 , b = -2

=> - (x+3) (x-2)


x = -3 ------- x = 2

Hope it hlpz.....
