Answer:-3([tex]x{2}-2x+3[/tex])

Step-by-step explanation:

[tex]-3x{2}+6x-9[/tex]

firstly we should find the common factor between [tex]-3x{2}[/tex] , 6x and -9, the common between them is -3

-3([tex]x{2}-2x+3[/tex])

and ([tex]x{2}-2x+3[/tex]) cannot factorize

Answer:

−3(x2 − 2x + 3).

Step-by-step explanation:

Given the equation:

−3x2 + 6x − 9

-3x2

Factors:

= 1, 3

+6x

Factors:

= 1, 2, 3

-9

Factors:

= 1, 3, 3

The common factor in the 3 terms are, 1 and 3.

Therefore,

= 3(−x2 + 2x − 3)

= -3(x2 - 2x + 3)
