Mathematics

Answer:

See below.

Step-by-step explanation:

x^2 - 6x + 1 = 0

x^2 - 6x = -1

We halve the coefficient of  x (which is -6/2 = -3) and square it, then add this to both sides:-

x^2 - 6x + (-3)^2 = -1 + (-3)^2

x^2 - 6x + 9 = -1 + 9

(x - 3)^2 = 8

x - 3 = ±√8

x =  3 ± √8

= 0.17, 5.83   to 2 decimal places.

What is 10 minutes before 9
Neporo4naja [7]
10 minutes before 9 is 8:50. since any time on the hour is at a perfect 60 minutes, you subtract the minutes given and move 1 hour back to find your answer.
for example, if you were asked what 20 minutes before 10 was. you start by subtracting 20 from 60. 60-20= 40, this being your minutes. 10-1 is 9, this being your hour, making the final answer 9:40.
