Question

4x2 - √3x - 5 = 0 by completing the square​

Answer 1

Roots of quadratic equation 4x2+3x+5=0 are complex roots. These complex roots can be found by taking the square root of the right hand side. Therefore, from above we can say that roots of the given quadratic equation are −3+√71i8and−3−√71i8 . So, the correct answer is “−3+√71i8and−3−√71i8 ”.
