The answer:
<span>the complement of the question may be 
Quadratic formula: x = -b +or- sqrt( b²-4ac)  / 2a

</span>the given equation is <span>0 = – 3x2 – 2x + 6 
generally, it is written as  ax² +bx + c = 0
so by doing coefficients identification method, 
we found  that  a = -3, b= -2 and c= 6

so x = </span> -b + sqrt( b²-4ac)  / 2a = 2 + sqrt(4 - 4*(-3)6) / -6 = - 9 or x = 10.6

A person who is 6ft tall walks away from a streetlight. When the person is 15 feet away from the light, the tip of his shadow is
Citrus2011 [14]
We essentially have a ratio here:
\frac{shadow}{actual}

Since we know the ratio is going to stay constant at \frac{5}{6}, we can use this to find the height of the lamp along with the information that the total distance from the lamp to the tip of his shadow is 20:
\frac{5}{6}=\frac{20}{h}
5h=120
h=24
