Question

What is the missing term? (-14y^2 + 9y^2 -12y +3) + (2y^2 +? -6y -2) = (-3y^2 -15y +1)

Answer 1

Answer:

3y

Step-by-step explanation:

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

• $-14y^2+9y^2+2y^2 = -3y^2$
• $-12y+-6y = -18y$
• $3+-2 = -1$

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.
