here we have to sum similar terms, and we have to apply the distributive property of multiplication over addition , in order to cancel the parentheses, so we can rewrite your expression as below: \( (8j3 – 10j2 – 7) – (6j3 – 10j2 – j + 12)= 8j3-6j3 -10j2+10j2+j -7-12=...\)
Okay i understand that and then i combined like terms and got the first answer
please, first combine like terms, and write what you get
we have: \(-10j^2+10j^2=0\)
So it would be B then?
Okay thank you I just got really confused because I know you have to switch the signs but idk lols thanks :)
