Mathematics

Sonbull [250]3 years ago
4 0
<span>If you have the equation
</span>x2<span> + 2x - 3 = 0
</span><span>You can factor the quadratic to get
</span><span>(x - 1)(x + 3) = 0
</span><span>and hence the roots
</span><span>x = 1 and x = -3
</span>
<span>Conversely, if you have the roots x = 1 and x = -3 you can recover the quadratic equation by forming (x - 1)(x + 3) = 0.
</span>
<span>(x - 5 - 3i)(x - 5 + 3i) = 0
</span><span>which simplifies to
</span>x2<span> - 10x + 34 = 0
</span>
hope this helped :)
