Question

X²+7x+6=0 alguem me ajuda rápido

Answer 1

${x}^{2} + 7x + 6 = 0$

$x = \frac{ - 7 + - \sqrt{ {7}^{2} - 4 \times 1 \times 6 } }{2 \times 1}$

$x = \frac{ - 7 + - \sqrt{49 - 24} }{2}$

$x = \frac{ - 7 + - \sqrt{25} }{2}$

$x = \frac{ - 7 + - 5}{2}$

$x = \frac{ - 7 + 5}{2} \\ x = \frac{ - 7 - 5}{2}$

$x = - 1 \\ x = - 6$
