    Multiply both sides by the common denominator and then make some order and then multiply both sides by -1:

    25-2x^2-3x+2=0\,\Longrightarrow\,2x^2+3x-27=0

    Now just solve this easy quadratic equation using the well known formula:

    x_{1,2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a} ....I think the solutions are -4.5\,,\,\,3 , but check this carefully.
