Question

factorise 27x³+125y³​

Answer 1

Step-by-step explanation:

27x^3+125y^3

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

(3x + 5y)((3x)^2 - (3x)(5y) + (5y)^2)

(3x + 5y)(3^2x^2 - 3x * 5y + (5y)^2)

(3x + 5y)(9x^2 - 3x * 5y + (5y)^2)

(3x + 5y)(9x^2 - 3x * 5y + 5^2y^2)

(3x + 5y)(9x^2 - 3x * 5y + 25y^2)

(3x + 5y)(9x^2 - 15xy + 25y^2)

The answer is .... (3x + 5y)(9x^2 - 15xy + 25y^2)

Answer 2

Answer

(3x+5y)(9x^2+15xy+25y^2)
