Question

What should be added to 8m2 – 5mp + 15p2
to get 4m2 – 7mp – 12p2
?

Answer 1

Answer:

-4m2 - 2mp - 27p2

Step-by-step explanation:

Let F(x) should be added

8m2 – 5mp + 15p2 + F(x) =  4m2 – 7mp – 12p2

F(x) = 4m2 – 7mp – 12p2 - (8m2 – 5mp + 15p2)

F(x) = 4m2 - 8m2 - 7mp + 5mp - 12p2 - 15p2

F(x) = -4m2 - 2mp - 27p2
