$- 63 z^{4} + 36 z^{3} - 54 z^{2} + 7 z^{3} - 4 z^{2} + 6 z - 35 z^{2} + 20 z - 30$

Step 1

Add $36 z^{3}$ and $7 z^{3}$ .

$- 63 z^{4} + 43 z^{3} - 54 z^{2} - 4 z^{2} + 6 z - 35 z^{2} + 20 z - 30$

Step 2

Subtract $4 z^{2}$ from $- 54 z^{2}$ .

$- 63 z^{4} + 43 z^{3} - 58 z^{2} + 6 z - 35 z^{2} + 20 z - 30$

Step 3

Subtract $35 z^{2}$ from $- 58 z^{2}$ .

$- 63 z^{4} + 43 z^{3} - 93 z^{2} + 6 z + 20 z - 30$

Step 4

Add $6 z$ and $20 z$ .

$- 63 z^{4} + 43 z^{3} - 93 z^{2} + 26 z - 30$
