Answer:
b) 2(x-6)(x+9)
Step-by-step explanation:
2x^2+6x-108
Factor out the 2, common factor!!!
2 (x^2 +3x -54)
Now time to factor, what to numbers multiply to get -54 and add to get 3
6,9 look good
what combination???
9,-6 because 9-6 = 3 and 9x-6=-54
so
2(x-6)(x+9)
From what I'm use to you put the 2 back in by dividing the numbers but in this case you dont need to.
SHAMALAMAMOOMOO :) :) :) :) :)
-1/12 - (-3/4)
= -1/12 + 3/4
= (-1+9)/12
= 8/12
=2/3
