x = .4384471872, x = 1, x = 4.561552813
Step-by-step explanation:
(x-1) is a root. When you divide it into x³-6x²+7x -2, you are left with x²-5x+2. Use the quadratic equation on that.
(5+/-)/2
So the roots are (5 - )/2, 1, and (5 + )/2

Answer:
x = 4
Step-by-step explanation:
Maybe you want to find x such that ...
2/7 = x/(x +10)
2(x +10) = 7x . . . . . . multiply by 7(x+10)
20 = 5x . . . . . . . . . . subtract 2x, simplify
4 = x . . . . . . . . . . . . divide by 5

<em>Additional comment</em>
You can almost solve this "by inspection" if you recognize the difference of the denominator and numerator is 5 on the left and 10 on the right. If you multiply the fraction on the left by 2/2, you get 4/14, the values in x/(x+10) in the fraction on the right.
