If r=-3, then it would be -3-12 which equals -15
Weird question wording. I take it should mean that this is a quadratic equation with solutions of x = -5 and x = 8. Then these are the factors: (x+5) and (x-8).
So
(x+5)(x-8) = 0 is the equation because x = -5 and x = 8 can make left-side equal to 0. But we expand so it becomes x² - 3x - 40 = 0
<span>(6, 4, 4, 5, 1, 8, 10, 7, 8, 6, 6, 7, 5, 4, 6)
</span>now arrange them
<span>1,</span>4, 4,4,5, 5,6,6,6,6,7,7,8,8,10
we have 15 numbers median is 8th number :second 6
first<span> quarterly is the last 4
third </span><span>quarterly is the second 7</span>
I think the answer to your question is going to be 14.13
