<p><b>Uus lehekülg</b></p><div>Harjutuse tähtaeg on '''3. praktikum''', mis toimub '''10.-11. veebruaril'''.<br />
<br />
== Kirjeldus ==<br />
<br />
Kirjutada funktsioon, mis leiab ruutvõrrandi lahendi. Ruutvõrrand on kujul <code>a * x^2 + b * x + c = 0</code>. Sellel võib olla mitu lahendit.<br />
<br />
Kui lahendeid on kaks, siis tagastada nende kahe argumendi korrutis. Kui lahendeid on üks, tagastada see lahend. Kui lahendeid pole, tagastada Double.NaN (see on üks konstant).<br />
<br />
== Ülesande esitamine ==<br />
<br />
Ülesanne tuleb laadida git repositooriumisse kausta "EX01".<br />
<br />
== Ülesande hindamine ==<br />
<br />
Ülesande hindamine toimub järgmises praktikumis. Eeldus on see, et lahendus on git'i üles laetud korrektselt.<br />
