Add: 'There are 2n eigenvalues that may be ...'.
Line 4:
:<math> Q(\lambda)x = 0\text{ and }y^\ast(\lambda) = 0,\, </math>
 
where ''Q''(λ) = λ<sup>2</sup>''A''<sub>2</sub>&nbsp;+&nbsp;λ''A''<sub>1</sub>&nbsp;+&nbsp;''A''<sub>0</sub>, with matrix coefficients ''A''<sub>2</sub>, ''A''<sub>1</sub> and ''A''<sub>0</sub> that are of dimension ''n''-by-''n''. There are 2n eigenvalues that may be ''infinite'' or finite, and possibly zero.
