Answer 4

Do you know what like terms are?

Answer 5

yes but i dont understand the signs i know your supposed to change them but im confused

Answer 6

oh okay :)

Always remember:

(+ ) (-) = (-) a positive multiplied by a negative is negative
(+)(+)= (+) a positive multiplied by a positive is positive
(-)(-)= (+) a negative multiplied by a negative is positive

\(\sf -(-2b^7)\) this is (-)(-)= (+) case

so it will be \(\sf +2b^7\)

Can you solve it from here?

Answer 7

ok so does that turn -15^7 into +15^7 as well?

Answer 8

what your saying is the equation should now be \[(15b ^{7}-7) - 2b ^{7}\]
