Multiple choice Roots of quadratic equation $\displaystyle\,2x\,-\,\frac{10}{x}\,=\,1$ are $\displaystyle\,2,\,\frac{5}{2}$ $\displaystyle\,-2,\,\frac{-5}{2}$ $\displaystyle\,-2,\,\frac{5}{2}$ None of these Reveal answer Fill a bubble to check yourself C Correct answer Explanation 2x - 10/x = 1. Multiply by x: 2x^2 - x - 10 = 0. (2x - 5)(x + 2) = 0. Roots are x = 5/2 and x = -2.
