Question

Find the roots of the quadratic equation x2+6x+9 = 0 answers​

Answer 1

Step-by-step explanation:

$let \: \alpha \: and \: \beta \: be \: the \: roots \: of \: quadratic \: {eq}^{n}$

$a = 1.$

$b = 6.$

$c = 9.$

Sum of the roots = $\alpha + \beta = \frac{ - b}{a}$

$= \frac{ - ( - 6)}{1}$

$= 6.$

Product of the roots = $\alpha . \beta = \frac{c}{a}$

$= \frac{9}{1}$

$= 9.$
