Answer:

Given : 61x³ + 27y³ + 180x²y  

To find : Factorize

Solution:

61x³ + 27y³ + 180 * x² * y

x = - 3y is one of the zero

lets check

61(-3y)³ + 27y³ + 180(-3y)²y

= 27y³ ( - 61 + 1   +  60)

= 27y³ (0)

hence x = - 3y is one of the zero

=> (x + 3y ) is one of the factor

                  61x²  - 3xy  + 9y²

x + 3y    _|   61x³ + 27y³ + 180x²y       |_

                  61x³   +        + 183x²y

                 ___________________

                            27y³   -   3x²y            

                                        - 3x²y   - 9xy²

                          __________________

                             27y³     +  0  +    9xy²

                             27y³       +          9xy²

                            __________________

                                    0

61x³ + 27y³ + 180x²y   = (x + 3y)(  61x²  - 3xy  + 9y²)
