Question

determine whether 2x^2+5root3x+16=0 has real roots or not. if having then find the roots

Answer 1

Answer:

Step-by-step explanation:

2x^2 + 5√3x+16 = 0

Here a=2, b = 5√3, c=16

For a quadratic equation to have real roots

b^2- 4ac > or = 0

(5√3)^2 - 4×2×16

= 25 × 3 - 128

=75 - 128

= -53

-53 < 0

Hence real roots does not exist
