Question

add the term -2m square ;-3mn; -3m square. ​

Answer 1

Answer:

Step-by-step explanation:

Step -1: Solving (i)

                 ⇒ 3mn +  ( - 5mn) + 8mn + ( - 4mn)

                 ⇒ 2mn

Step -2: Solving (ii)

                 ⇒ (t - 8tz) + (3tz - z) + (z - t)

                 ⇒ t(1 - 1) + tz( - 8 + 3) + z( - 1 + 1)

                 ⇒ - 5tz

Hence On adding the variables, we get 2mn and - 5tz respectively.

Answer 2

Answer:

(-2m^2)+(-3mn)+(-3m^2)

= -2m^2-3mn-3m^2

= -5m^2-3mn

= -m(5m+3n)
