9x²+6x=0
3x(3x+2) = 0
- By zero product property
3x = 0
x = 0/3
x = 3
[tex] \\ [/tex]
3x+2 = 0
3x = 0 - 2
3x = -2
x = -2/3
[tex] \\ [/tex]
Checking:
- 9x²+6x = 0
- 9(0)²+6(0) = 0
- 9(0) + 0 = 0
- 0 + 0 = 0
[tex] \\ [/tex]
- 9x²+6x = 0
- 9(-2/3)² + 6(-2/3) = 0
- 9(4/9) + 2(-2) = 0
- 4 - 4 = 0

[tex]\large\underline{ \mathcal {ANSWER}}:[/tex]
- The roots are 0 and -2/3
