Question

. Find the discriminant of quadratic equation 2x²-16x + 30 = 0
and hence find the nature of the roots.​

Answer 1

Step-by-step explanation:

D=b²-4ac

=(-16)²-4(2)(30)

=256-240

=16

therefore, D>0

hence, roots are real

Answer 2

Answer:

bhai yaar Hamen pata hai ki discriminant ak

real number hai

Therefore

D= b²-4ac

D= (-16)² -4×2×30

D= 256-240

D=16

Now

if bhai discriminant Agar zero Se Bada Aaye To iska matlab hai

x = -B ± √D / 2a

x= -(-16)+√16 /2×2. and -(-16)-√16 / 2×2

x= 4 and 3 ans
