Answer:
b-2 i think. Im pretty sure its right if not sorry
<span>Mixed numbers from 6 to 7 with an interval of 1/5 between each pair of mixed numbers are {6 1/5, 6 2/5, 6 3/5, 6 4/5}</span>
<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 :)
