Answer: 8 (2y-1)
Step-by-step explanation: first start by writing like this below:
16y-8
Then factorise the numbers(cut the numbers)
2×2×2×2×y - 2×2×2
Now take all which is common like:
2×2×2=8
Then,take the remained numbers and add it into the brackets.
8 (2y - 1) Here, why we should put 1,because there's nothing left.
If you want to check the answer, factorise this expression and see:
8 (2y-1)
16y-8.
