 Question from Tony: express x/a -2a/x =-1 in terms of a.

Hi Tony,

I would first eliminate the fractions.

Multiply each side of the equation by $a$ and simplify. Multiply both sides of the resulting equation by $x$ and simplify. Now you have no fractions. Write the resulting equation as a quadratic ina and solve for $a.$

Write back if you need more assistance,
Penny
