Answer 2

Answer:

1/324(6x-1+√37)(6x-1-√37)

Step-by-step explanation:

• 9x² -3x -9=
• 1/9(x²-x*1/3-1)=
• 1/9(x²-2x*1/6+1/36-1/36-1)=
• 1/9(x²-2x*1/6+1/36-37/36)=
• 1/9(x-1/6)²-1/9*37/36=
• 1/9(x-1/6)²-1/9*(√37/6)²=
• 1/9(x-1/6+√37/6)(x-1/6-√37/6)=
• 1/9*1/6(6x-1+√37)1/6(6x-1-√37)=
• 1/324(6x-1+√37)(6x-1-√37)
