Question

Simplify (8j3 – 3j2 + 5) – (4j3 + 8j2 + 7j – 6)

Answer 1

(8j^3-3j^2+5) - (4j^3+8j^2 + 7j - 6)
1 step is to distribute the neg sign in front of the the 2nd set of ( )
do this mult everything in it by negative 1
then get rid of the parentheses

that will give you
8j^3-3j^2+5 - 4j^3 - 8j^2 - 7j + 6) , then just combine like terms
