Answer:

3y

Step-by-step explanation:

The missing term is 3y since the following like terms combine:

  • [tex]-14y^2+9y^2+2y^2 = -3y^2[/tex]
  • [tex]-12y+-6y = -18y[/tex]
  • [tex]3+-2 = -1[/tex]

These terms are the same as the sum listed except -18y.

What must be added to -18y +____=-15y.

-18y+_3y__ =-15y

3y is the solution.
