  1. Solve the equation $\displaystyle -2\,x^2+3\,x+1=0$.

    $\displaystyle \left[ x=-{{\sqrt{5}+3}\over{2}} , x={{\sqrt{5}-3}\over{2}} \right] $ $\displaystyle \left[ x=1 , x={{1}\over{2}} \right] $ $\displaystyle \left[ x=-{{\sqrt{17}-3}\over{4}} , x={{\sqrt{17}+3}\over{4}} \right] $ $\displaystyle \left[ x=-{{\sqrt{17}+3}\over{4}} , x={{\sqrt{17}-3}\over{4}} \right] $

  2. If a linear function f satisfies f(2) = 5 and f( − 3) = 3, find f(x).

    $\displaystyle y={{2\,x}\over{5}}-{{21}\over{5}}$ $\displaystyle y={{5\,x}\over{2}}+{{21}\over{2}}$ $\displaystyle y={{2\,x}\over{5}}+{{21}\over{5}}$ $\displaystyle y={{5\,x}\over{2}}-{{21}\over{2}}$
