I)(2x +3y) (4x²-6xy +9y²)
ii) (a+b+c(a2²+b²+ c²–ab –bc-ca)​

Answer 1

i) (2x+3y)(4x²-6xy+9y²)

= 8x²-12x²y+18xy²+12x²y-18xy²+27y²

= 8x³+27y³

Hope it helps

Answer 2

Answer:

1) (2x+3y) (4x²-6xy +9y²)

= 2x(4x²-6xy +9y²) + 3y(4x²-6xy +9y²)

=8x³- 12x²y +18xy² + 12x²y- 18xy²+ 27y³

=8x³ + 27y³

hope it will help you !!!!!
