Answer 2

Answer:

$\boxed{\bf\red{ x\implies: \frac{ - 5 + \sqrt{15} }{10} }} \: \: \: \: \: \: \tt\ \underline{or} \: \: \: \boxed{\bf\purple{ x\implies: \frac{ - 5 - \sqrt{15} }{10} }}$

Step-by-step explanation:

$\tt\underline{using \: quadratic \: formula \mapsto: \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a} } \\ \\ \sf\ {5x}^{2} + 10x + 2 \\ \\ \tt\ x\implies: \frac{ - b± \sqrt{ {b}^{2} - 4ac} }{2a} \\ \\ \tt\ x\implies: \frac{ - 10± \sqrt{ {(10)}^{2} - 4 \times 5 \times 2} }{2 \times 5} \\ \\ \tt\ x\implies: \frac{ - 10± \sqrt{100 - 40} }{1} \\ \\ \tt\ x\implies: \frac{ - 10± \sqrt{60} }{10} \\ \\ \tt\ x\implies: \frac{ - 10±2 \sqrt{15} }{10} \\ \\ \tt\ x\implies: \frac{ - 5±\sqrt{15} }{5} \\ \\ \boxed{\bf\red{ x\implies: \frac{ - 5 + \sqrt{15} }{10} }} \: \: \: \: \: \: \tt\ \underline{or} \: \: \: \boxed{\bf\purple{ x\implies: \frac{ - 5 - \sqrt{15} }{10} }}$
