${x}^{2} + 7x + 6$
​

Answer 1

Answer:

$x= - 1 \: \: \: \: \: \: \: \: - 6$✔✔

Step-by-step explanation:

SOLUTION-

${x}^{2} + 7x + 6 \\ d = { {b}^{2} - 4ac } \\ \: \: \: \: = 49 - 24 \\ \: \: \: \: = 25 \\ x = \frac{ - b + - \sqrt{d} }{2a} \\ \: \: \: \: = \frac{ - 7 + 5}{2} \: \: \: \: \: \: \: \: \frac{ - 7 - 5}{2} \\ \: \: \: \: = - 1 \: \: \: \: \: \: \: \: - 6$
