not really

Answer 21

that one was a guess

Answer 22

okay so the numbers need to mulitply together to become the last term in the problem in this case -30. the negative tells you that one of the numbers need to be negative. those two numbers also have to add together to be the middle term in this case 1. 6+(-5) is and and 6*-5 is -30. sorry if that was confusing..

Answer 23

Oh no i get it ci thought it was because of -30 but i wasnt sure
