Answer:

The other addend is
15\cdot a^(2)\cdot b^(2)-20\cdot a^(2)\cdot b + 6\cdot a \cdot b^(2)-4\cdot a \cdot b +7.

Explanation:

The other addend is determined by subtracting
-5\cdot a^(2)\cdot b^(2)+12\cdot a^(2)\cdot b-5 from
10\cdot a^(2)\cdot b^(2)-8\cdot a^(2)\cdot b + 6\cdot a\cdot b^(2)-4\cdot a \cdot b + 2:


x = 10\cdot a^(2)\cdot b^(2)-8\cdot a^(2)\cdot b + 6\cdot a \cdot b^(2)-4\cdot a \cdot b + 2 - (-5\cdot a^(2)\cdot b^(2)+12\cdot a^(2)\cdot b -5)


x = 10\cdot a^(2)\cdot b^(2)-8\cdot a^(2)\cdot b + 6\cdot a \cdot b^(2)-4\cdot a \cdot b +2 +5\cdot a^(2)\cdot b^(2)-12\cdot a^(2)\cdot b+5


x = (10\cdot a^(2)\cdot b^(2)+5\cdot a^(2)\cdot b^(2))-(8\cdot a^(2)\cdot b+12\cdot a^(2)\cdot b)+6\cdot a \cdot b^(2)-4\cdot a \cdot b +7


x = 15\cdot a^(2)\cdot b^(2)-20\cdot a^(2)\cdot b + 6\cdot a \cdot b^(2)-4\cdot a \cdot b +7

The other addend is
15\cdot a^(2)\cdot b^(2)-20\cdot a^(2)\cdot b + 6\cdot a \cdot b^(2)-4\cdot a \cdot b +7.
