Question

1 4

. Find the value of discriminant of the quadratic equation 5m? - m = 0
Write down the formula of median​

Answer 1

`D = 1` --- Determinant

`M = (N+1)/(2)th` --- Median

Explanation:

Given

`5m^2 - m = 0`

Required

Calculate the determinant (D)

This is calculated using

`D = b^2 - 4ac`

In
`5m^2 - m = 0`

`a = 5`,
`b = -1` and
`c = 0`

So, we have:

`D = b^2 - 4ac`

`D = (-1)^2 - 4 *5*0`

`D = 1 - 0`

`D = 1`

(b) Median Formula.

Median (M) is calculated using:

`M = (N+1)/(2)th` item
