Question 770341
<pre>
You've proceeded correctly so far!
Continue from the last equation
-2X+(60/X) = 7
Multiplying by x
-2*x^2 + 60 = 7*x
{{{2*x^2 + 7*x - 60 = 0}}}
This is a standard quadratic equation which can be solved by factorizing
{{{2*x^2 - 8*x + 15*x - 60 = 0}}}
{{{(2*x + 15)*(x - 4) = 0}}}
So the 2 roots are
2*x + 15 = 0, or x = -15/2
x - 4 = 0, or x = 4
Hope you got it :)
