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

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

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

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