Question

What must be added to 8m^2 minus 3mn minus 6 to get 16m^2 minus 5mn plus 4

Answer 1

Step-by-step explanation:

Given 8m^2-3mn-6

We have to get 16m^2-5mn+4

Let the required number be 'X'

(8m^2-3mn-6)+X=16m^2-5mn+4

X=(16m^2-5mn+4)-(8m^2-3mn-6)

X=8m^2-2mn+10

The final answer is

8m^2-2mn+10
