Answer 2

Step-by-step explanation:

Step by step solution :

Step 1 :

Equation at the end of step 1 :

(a2) - (81 • (b - c) • 2)

Step 2 :

Equation at the end of step 2 :

(a2) - 162 • (b - c)

Step 3 :

Trying to factor a multi variable polynomial :

3.1 Factoring a2 - 162b + 162c

Final result :

a2 - 162b + 162c
