Answer 2

Answer:

${x}^{2} - 15x + 50 = 0 \\ x = \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a} \\ x = \frac{ - ( - 15)± \sqrt{ {( - 15)}^{2} - 4 \times 1 \times 50 } }{2 \times 1} \\ x = \frac{15± \sqrt{225 - 200} }{2} \\ x = \frac{15± \sqrt{25} }{2} \\ x = \frac{15±5}{2} \\ x = \frac{15 + 5}{2} \: \: \: or \: \: \: x = \frac{15 - 5}{2} \\ x = \frac{20}{2} \: \: \: or \: \: \: x = \frac{10}{2} \\ \boxed{ \large x = \underline{ \underline{ 10}} \: \: \: or \: \: \: x = \underline{ \underline{5}}}$
