Step-by-step explanation:

Combine like terms

a. -8p + (-9p) + (-2p) = -8p -9p -2p = (-8 - 9 - 2)p = -19p

b. -3jk + 5jk + (-6jk) = -3jk + 5jk - 6jk = (-3 + 5 - 6)jk = -4jk

Terms are called "like terms" if they have the same variable part (the same letters in the same powers). Like terms differ at most coefficient.

Answer:

a. –8p + (–9p) + (–2p)

Combine the coefficients of the like monomials.

[(–8) + (–9) + (–2) = –19]

Answer:  –19p

b. –3jk + 5jk + (–6jk)

Combine the coefficients the like of monomials.

[(–3) + 5 + (–6) = –4]

Answer: –4jk
