Question

factorise 27Y²+125X³​

Answer 1

Answer:

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

Step-by-step explanation:

Here, As per our given question,

=27y^3+125x^3

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

Here, The identity which is used :(a)^3+(b)^3=(a+b) (a^2+b^2-ab)

So,=(3y+5x) [(3y)^2+(5x)^2-(3y)×5(x)]

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

Hence, It is the answer,

Thank you.
