Question

if one root of the equation 2x2 -6x +c =0 is 3+5i/2 then value of c will be
​

Answer 1

Step-by-step explanation:

If one root of the equation

$2 {x}^{2} - 6x + c = 0$

is (3+5i)/2 then the other root of this equation is (3-5i)/2. Hence the product of the roots =>2(3+5i)(3-5i)/4 =>(9-25(-1))/2 =>17. Hope it helps you.
