Question

factorise this question and tell me the answer fast

Answer 1

125x^3+y^3

=(5x)^3+(y)^3

using identity a^3+b^3=(a+b)(a^2-2ab+b^2)

=(5x+y)(25x^2-5xy+y^3)

Answer 2

given that,

$125 {x}^{3} + {y}^{3}$
=(5x)^3+y^3
this is in the form of

(a^3+b^3)=(a+b)(a^2+b^2-ab)
=(5x+y)((5x)^2+y^2-5x*y)
=(5x+y)(25x^2+y^2-5xy)

pls mark as brainliest.
