Answer:
3 ( x - 3) ( x + 1)
Step-by-step explanation:
I believe the question is
-6x² + 15x + 9
Multiply -6 by 9 = -54
To factorise you find the factor of -54 that will add up to +15.
The factors = 18 & -3.
Rewrite equation by replacing the 15x by the factors.
-6x² + 18x - 3x + 9
Factorise
-6x(x - 3) -3 ( x - 3 )
(x - 3) ( -6x - 3)
(x - 3) -3( x + 1)
-3 ( x - 3) ( x + 1)
