Question

The roots of the quadratic equation 5x2 - 4x + 5 = 0 are​

Answer 1

(2+42 i)/5 and 2-42i /5.

Roots are imaginary roots

hope it helps you

Answer 2

Answer:

Roots of

$</p><p>5x^2-4x+5=0$

are

$\frac{ - b + \sqrt{b^2 - 4ac}}{2a} \: \: and \: \: \frac{ - b - \sqrt{b^2 - 4ac}}{2a}$

Now put the value and find the roots....

$\frac{ 4 + \sqrt{4^2 +100}}{10} \: \: and \: \: \frac{ 4 - \sqrt{4^2+100}}{10}$

$\frac{ 4+ \sqrt{116}}{10} \: \: and \: \: \frac{ 4 - \sqrt{116}}{10}$

$\frac{ 2+ \sqrt{29}}{5} \: \: and \: \: \frac{ 2- \sqrt{29}}{5}$

If simplified further, the roots are - 0.677 and 1.477
