Los op vir x en kies die regte antwoord as \( - 2{x^2} + x = 2 \)
\( \begin{align}
- 2{x^2} + x &= 2\\
- 2{x^2} + x - 2 &= 0\\
x &= \frac{{ - b \pm \sqrt {{b^2} - 4ac} }}{{2a}}\\
x &= \frac{{ - \left( 1 \right) \pm \sqrt {{{\left( 1 \right)}^2} - 4\left( { - 2} \right)\left( { - 2} \right)} }}{{2\left( { - 2} \right)}}\\
& = ERROR\\
&\therefore {\rm{geen}}\,\,{\rm{re}}\ddot ele\,\,{\rm{oplossing}}
\end{align} \)
