Question

.solve the 2 one circle one​

Answer 1

Answer:

-1

Step-by-step explanation:

5m²-m=0

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

Discriminant = b² - 4ac

= (-1)²-4(5)(0)

= 1-0

= 1

Answer 2

Answer:

1(nature is real & unequal)

Step-by-step explanation:

${5m}^{2} - m = 0$

compair with

${ax}^{2} + bx + c = 0$

now,

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

now,

discriminent=

$= {b}^{2} - 4 ac \\ = { (- 1)}^{2} - 4 \times 5 \times 0 \\ = 1 - 0 \\ = 1$
