9.	Determine the nature of the roots for
Answer» First, we'll have to find the discriminant, D = b² - 4ac If D > 0 we will have REAL and DISTINCT roots If D < 0 we will have IMAGINARY roots If D = 0 we will have real and equal roots In this quadratic equation, 3x² - 5x + 7 = 0 a = 3, b = -5, c = 7 Now, D = b² - 4ac = (-5)² - 4(3)(7) = 25 - 84 = -59 < 0 Thus D < 0, which indicates that the given equation 3x² - 5x + 7 = 0 has imaginary roots. Hope it helps!!

9.

Determine the nature of the roots for

Answer»

First, we'll have to find the discriminant, D = b² - 4ac

If D > 0 we will have REAL and DISTINCT roots

If D < 0 we will have IMAGINARY roots

If D = 0 we will have real and equal roots

In this quadratic equation, 3x² - 5x + 7 = 0

a = 3, b = -5, c = 7

Now, D = b² - 4ac = (-5)² - 4(3)(7) = 25 - 84 = -59 < 0

Thus D < 0,

which indicates that the given equation 3x² - 5x + 7 = 0 has imaginary roots.

Hope it helps!!

28.	The 8/9th term of A.P is zero prove that its 29th term is divisible its 19th term
Answer» LET first term be a,common difference be d. Given.9th term is zero. therefore , a + (9 - 1)d =0 ,--> a + 8d =0 ....(1) 19th term = T19= a + (19 -1)d =a + 18d = -8d + 18d =10d ( a = -8d from EQN. (1) ). Similarly, T29 =a + (29 -1 )d= a + 28d = = -8d +28d =20d therefore, T19 = 10d and T29 = 20d Here we can simply SEE that T29 = 2 times of T19, 29TH term is DIVISIBLE by 19th term.
