Question

find the nature of the roots of the equation 2n²+5n-1=0​

Answer 1

Answer:

real and distinct roots.

Step-by-step explanation:

here, a=2 , b=5 , c=(-1)

we know ,

D = b^2 - 4×a×c

D = 5^2 - 4×2×(-1)

D = 25 + 8

D = 33

since , D=33 > 0

therefore , the quadratic equation has ---

REAL AND DISTINCT ROOTS.
