We have that
<span>6x^2 +12x+5=0
to find the x intercepts resolve the second order equation
x=[-b(+-)</span>√(b²-4ac)]/2a
x1=[-12(+)√(12²-4*6*5)]/12---> [-12(+)√(144-120)]/12
=[-12(+)√(24)]/12--------> -1+√24/12-----> -1+√6/6
x1=-1+√6/6
so
x2=-1-√6/6
see the graph in the attached figure
<span>
the answer is
</span>the x-intercepts for the graph of the quadratic function in <span>exact form are
</span>x1=-1+√6/6
x2=-1-√6/6
The conclusion is incorrect due to the fact that the sample is biased
Take a random sample of 50 from a student population, such as an english class
The reciprocal of -1/3 is -3/1
and the reciprocal of 4/1 is 1/4
B. Point F, B, and C are coplanar
In fact, A is wrong, because you can't draw a line passing through D, G, and F
Also, C is wrong because point E is not on the orange plane
For the same reason, D is wrong because line AE seems perpendicular to the plane, but anyway it surely does not lie on the plane
