-- 5 [ (-- 2)(-- 3) + 9 ]
= -- 5 [ 6 + 9 ] as (-- 2)(-- 3) = 6

Hi:-)
If it's multiplied:
-5((-2)(-3)+9) -the original equation
You get 6 when you multiply -2 and -3 as 2x3=6 and if you multiply two negative numbers you get a positive number that's why it's 6 not -6.
6+9=15 and 15 is what you get from brackets.Multiply -5 by 15 and you'll get
-75 as if you multiply negative and positive number you get a negative one.So your answer is -75
In full:
-5((-2)(-3)+9)=-5(6+9)=-5x15=-75
Hope it helped:-)
