Please help me =(


(Complete solution please )​

Answer 1

#1

`\\ \sf\longmapsto y^3+27`

`\\ \sf\longmapsto y^3+3^3`

• Use a^3+b^3 formula

`\\ \sf\longmapsto (y+3)(y^2-3y+9)`

#2

`\\ \sf\longmapsto 8-y^3`

`\\ \sf\longmapsto 2^3-y^3`

`\\ \sf\longmapsto (2-y)(2^2+2y+y^2)`

`\\ \sf\longmapsto (2-y)(4+2y+y^2)`

#3

`\\ \sf\longmapsto x^3+y^3`

`\\ \sf\longmapsto (x+y)(x^2+xy+y^2)`

#4

`\\ \sf\longmapsto m^3-216`

`\\ \sf\longmapsto m^3-6^3`

`\\ \sf\longmapsto (m-6)(m^2-6m+36)`
