15t-(t-4)

I don't have any idea how to do this

Well, I will help you but only by showing you how it's done.

Take the 15t and leave it alone.

Take the second part... -(t-4)

Think about it by itself.

What does it mean? It means the opposite of what's stated.

So, what's negative +t? What's negative -4?

Switch the signs.

Once you've done that, you can go back and consider the 15t portion.

15t minus the negative of t minus the negative of negative 4 equals what?

Won't give you the answer. You need to learn it. :)

15t-(t-4)
15t+-1(t-4)
15t-t+4
14t+4

-
-15t^2 + 60t
