i could explain...so

Answer 6

If we put it into the ca + cb form, we get -2(2u) + -2(-1)

Answer 7

In this case c = -2, a = 2u and b = -1.
If we were to but it back into c(a+b), we get -2(2u+-1), this is the same as -2(2u-1)

Answer 8

two minus give a plus,
you should multiply a digit or symbol to each symbol or digit in the parentheses
