Sir thanku so much for such a great explanation ❤️

[ShadiaNkomo-sung]

Thank u sm u are really a good teacher I feel less worried for my test❤❤❤❤❤😊

What if you are asked for the value of K for which the equation has one real room

[adgfx]

a)have same roots when k^2-400=0=>k=plus or minus 20.(b)different roots when k^2-400>0.(c)roots are imaginary when k^2-400<0.(d)same as (b)

Your video is good but From my opinion you should speak Hindi then it will be more comfortable for students
Thanks

Can you use equation: x^4 - 4x^2 + x + k = 0

[theophonchana]

b^(2) - 4ac > 0
k^(2) - 4 × 5 × 20 > 0
k^(2) - 400 > 0
k^(2) > 400
k > 20
