Step-by-step explanation:
D=b²-4ac
=(-16)²-4(2)(30)
=256-240
=16
therefore, D>0
hence, roots are real

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
