Find all real number solutions: 3x^(-2) + 7x^(-1) + 2 = 0 If there is more than one solution, separate them with commas.
Added by Sierra C.
Step 1
To do this, we can multiply every term in the equation by x^2 to get rid of the denominators: 3x^(-2) * x^2 + 7x^(-1) * x^2 + 2 * x^2 = 0 This simplifies to: 3 + 7x + 2x^2 = 0 Show more…
