ANSWER : 6(6x-10)
Step-by-step explanation:
1) Highest common factor is 6, as 36 and 60 are both divisible by 6.
2) Take the highest common factor (6) outside of brackets and throw everything else inside the brackets.
3) 6 times ?= 36x
?= 6x so we get: 6(6x___)
4) 6 times?= -60
?= -10 so we get: 6(__-10)
5) Combine your knowledge of both and get the answer: 6(6x-10)
