Question

a³+125b³, Factorize the given equation.

Answer 1

Thanks for asking the question

a^3+(5b)^3

so

formula

a3+b3 = (a+b)(a2-ab+b2)

a^3+5b^3 = (a+5b)(a^2-5ab+25b)

have a nice day

Answer 2

Answer:

a³ + 125b³ =(a+5b)(a²-5ab+25b²)

Step-by-step explanation:

************************************

We know the algebraic identity :

x³ + y³ = ( x + y )( x² - xy + y² )

*************************************

Here ,

a³ + 125b³

= a³ + ( 5b )³

= (a+5b)[ a² - a×5b + ( 5b )² ]

= (a+5b)( a² - 5ab + 25b² )
