$- 81 m^{2} - 17 m n + 15 n^{2} + 20 m^{2} + 3 m n - 17 n^{2} + 53 m^{2} + 18 m n + 7 n^{2}$

Schritt 1

Addiere $- 81 m^{2}$ und $20 m^{2}$ .

$- 61 m^{2} - 17 m n + 15 n^{2} + 3 m n - 17 n^{2} + 53 m^{2} + 18 m n + 7 n^{2}$

Schritt 2

Addiere $- 61 m^{2}$ und $53 m^{2}$ .

$- 8 m^{2} - 17 m n + 15 n^{2} + 3 m n - 17 n^{2} + 18 m n + 7 n^{2}$

Schritt 3

Addiere $- 17 m n$ und $3 m n$ .

$- 8 m^{2} + 15 n^{2} - 14 m n - 17 n^{2} + 18 m n + 7 n^{2}$

Schritt 4

Subtrahiere $17 n^{2}$ von $15 n^{2}$ .

$- 8 m^{2} - 2 n^{2} - 14 m n + 18 m n + 7 n^{2}$

Schritt 5

Addiere $- 2 n^{2}$ und $7 n^{2}$ .

$- 8 m^{2} + 5 n^{2} - 14 m n + 18 m n$

Schritt 6

Addiere $- 14 m n$ und $18 m n$ .

$- 8 m^{2} + 5 n^{2} + 4 m n$
