Question

HELP!
identify the error made in simplifying this expression. 6p(-2p-5p)=-p

Answer 1

a + sign is missing

Answer 2

6p+(-2p-5p)=-p

Answer 3

6p(-2p-5p)=
6p(-7p)
this is where the error occurred. they added instead of multiplying

Answer 4

6p+(-7p)=-p
but
6p(-7p)=-42p^2

Answer 5

Answer 6

or as mik_wind said they missed the '+' sign
