Question

factorise:- 6-x-x² by spilliting​

Answer 1

Step-by-step explanation:

$(2 - x) \: \: \: (3 + x) \: are \: factors \: of \: given \: quadratic \: expression \: 6 - x - x {}^{2} \\ \\ given \: quadratic \: expression \\ 6 - x - x {}^{2} \\ \\ splitting \: the \: middle \: term \\ we \: get \\ \\ 6 - 3x + 2x - x {}^{2} \\ 3(2 - x) + x(2 - x) \\ take \: (2 - x) \: common \: \\ we \: get \\ \\ (2 - x)(3 + x) \\ therefore \\ \\ 6 - x - x {}^{2} = (2 - x)(3 + x)$

Answer 2

Answer:

6- x- x^2 =) 6- 3x+2x -x^2 =) 3( 2-x) + x ( 2-x ) =) (2-x)(3+x) =) x = -3 and x = 2
