Question

find the value of discriminant of the quadratic equation
${5m}^{2} - m = 0$
​

Answer 1

Answer:

5m2 - m = 0

5m2 - m = 0 5m2 = m

5m2 - m = 0 5m2 = m5m =m/m

5m2 - m = 0 5m2 = m5m =m/m5m = 1

5m2 - m = 0 5m2 = m5m =m/m5m = 1m = 1/5

Answer 2

Answer:

on comparing the given equation with ax

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

we get a=5,b=2,c=1

$b {}^{2} - 4ac = 2 { }^{2} - 4 \times 5 \times 1 \\ 4 - 20 \ \\ \sqrt{} 16 \\b {}^{2} { - 4ac = } 4$

Therefore discriminant is 4
