Answer:
a = 9 , b = -6 and c = -2
D = b² - 4ac
So, D = (-6)² - 4(9)(-2) = 36 + 72 = 108
Since, D > 0
⇒ Roots are Real and different.
Step-by-step explanation:
nature of the roots depend on the value of discriminant,
1.If D > 0,then roots are real and different.
2.If D = 0,then roots are real and same.
3.If D < 0, then roots do not exist or it is a complex number...
