- We have a bag with 4 white chips and 6 black chips
- Question : What is the probability of randomly choosing a white chip, not replacing it, and then randomly choosing another white chip?
4 white and 6 black
4 + 6 = 10
Choosing the first white chip :
Since we took one out , now
3 white chips , 6 black chips
3 + 6 = 9
Choosing another white chip :

Answer:
(x + 8) (x - 8)
Step-by-step explanation:
To factorise the expression follow the steps:
Think the factorising means you want like:-
( x + _ ) ( x + _ )
Now, add the numbers to get 0 & multiple together to get -64
-64 = 8 x -8
8 + -8 = 0
Now fill the numbers in the factorising mean which will give you,
( x + _ ) ( x + _ ) --> ( x + <u>8</u> ) ( x - <u>8</u> )
Therefore, the answer will be: ( x + <u>8</u> ) ( x - <u>8</u> )
I hope this will help you :)
