Question

What are product of roots of x^2+15x+9=0​

Answer 1

Answer:

${x}^{2} + 15x + 9 \\ x= \frac{ - 15 - \sqrt{189} }{2} = \frac{ - 15 - 3 \sqrt{21} }{2} = - 14.374$

$x = \frac{ - 15 + \sqrt{189} }{2} \\ = \frac{ - 15 + 3\sqrt{21} }{2} = - 0.626$

product of roots = (-14.374)×(-0.626)

= 8.998124
