Question

125 a3 + b3 +64c3 - 60 abc​

Answer 1

Step-by-step explanation:

125a³ + b³ + 64c³ - 60abc (Given)

Now, by Using formula of :

$\tiny\bigstar \: \: \underline{ \boxed{\sf a^3 + b^3 + c^3 - 3abc = (a + b + c) (a^2 + b^2 + c^2 - ab - bc - ca)}} \: \: \bigstar$

Calculation :

(5a)³ + b³ + 4c³ - 3(5a) b(4c)

(5a + b + 4c) [(5a)² + b² + (4c)² - 5ab - 4bc - 20ca]

(5a + b + 4c) (25a² + b² + 16c² - 5ab - 4bc - 20ca)
