Question

Factorizar 27b³ + 8c³

Answer 1

Respuesta:

a³+27b³+8c³-18abc

(a)³+(3b)³+(2c)³-3xax3bx2c

We know the formula that a³+b³+c³-3abc=(a+b+c)(a²+b²+c²-ab-bc-ca)

where a=a,b=3b,c=3c

(a+3b+2c){(a)²+(3b)²+(2c)²-ax3b-3bx2c-2cxa)

(a+3b+2c)(a²+9b²+4c²-3ab-6bc-2ca)     ..........................(ANS)
