There are two solutions to 
<script type="math/mml"><math xmlns="http://www.w3.org/1998/Math/MathML">
  <mi>a</mi><msup><mi>x</mi><mn>2</mn></msup>
  <mo>+</mo> <mi>b</mi><mi>x</mi>
  <mo>+</mo> <mi>c</mi> <mo>=</mo> <mn>0</mn>
</math></script>
and they are
<script type="math/mml"> <math mode="display" xmlns="http://www.w3.org/1998/Math/MathML"> <mi>x</mi> <mo>=</mo> <mrow> <mfrac> <mrow> <mo>&#x2212;<!-- - --></mo> <mi>b</mi> <mo>&#x00B1;<!-- --></mo> <msqrt> <msup><mi>b</mi><mn>2</mn></msup> <mo>&#x2212;<!-- - --></mo> <mn>4</mn><mi>a</mi><mi>c</mi> </msqrt> </mrow> <mrow> <mn>2</mn><mi>a</mi> </mrow> </mfrac> </mrow> <mtext>.</mtext> </math> <script>
