Question

expand the following expression, 8a (y-1)​

Answer 1

Answer:8ay-8a

Step-by-step explanation

All you have to do is times 8a by everything in the brackets.

So it will be 8a times y which makes 8ay,

then you do 8a times -1 which is -8a.

Normally you would add both your answers together to get the final answer if they were like terms. But in this case they are not.

So the answer is just 8ay-8a.
