​

Answer 1

Answer:

hey dude!

your answer is...

Step-by-step explanation:

$x {}^{2} - 7x + 1 = 0 \\ x = \frac{ - ( - 7) + - \sqrt{( - 7) {}^{2} - 4 \times 1 \times 1} }{2 \times 1} \\ x = \frac{7 + - \sqrt{49 - 4} }{2} \\ x = \frac{7 + - \sqrt{45} }{2} \\ x = \frac{7 + - 3 \sqrt{5} }{2} \\ x = \frac{7 + 3 \sqrt{5} }{2} . \\ x = \frac{7 - 3 \sqrt{5} }{2} . \\ hope \: its \: helps....$
