Coz im not good at math

Sagot :

Number one: 20 Number two: 9x^2 - 16y^2 Number three: x^2 + 4xy + 2xz + 4y^2 + 4yz + z^2 Number four: n^3 +6n^2 + 12n + 8 Number five: -y^3 - 9y^2 - 27y or 1 *insert long fraction bar here* y^3 + 9y^2 + 27y + 27

1. 4 * 5 = 20 or you can also do FOIL: 14+21-6-9 = 20
2. Difference of two squares: 9x²-16y²
3. x²+4y²+z²+4xy+4yx+2xz
4. n³+6n²+12n+8
5. 1 / [y³+9y²+27y+27]
