Question 190570
Well, if you started with:
{{{5 + 1/x - 1/x^2 = 0}}}
.
To rid yourself of all denominators, multiply BOTH sides by x^2 (common denominator):
{{{x^2(5 + 1/x - 1/x^2) = x^2(0)}}}
Distributing the x^2:
{{{5(x^2) + (1/x)(x^2) - (1/x^2)(x^2) = 0}}}
{{{5x^2 + x^2/x - x^2/x^2 = 0}}}
Through cancellation we get:
{{{5x^2 + x - 1 = 0}}}
