Michele correctly solved a quadratic equation using the quadratic formula as shown below.
Fofino [41]

Answer:

The original equation must have been:

7x^{2} -5x-2=0

Step-by-step explanation:

A quadratic equation is in the form of :

ax^{2} +bx+c=0

And it is solved in the form of :

x=\frac{-b+\sqrt{b^{-4ac} } }{2a} and x=\frac{-b-\sqrt{b^{-4ac} } }{2a}

Now the given equation is :

x=\frac{-(-5)+-\sqrt{(-5)^{2} -4(7)(-2)} }{2(7)}

We can see that here;

a = 7

b = -5

c = -2

So, the original equation must have been:

7x^{2} -5x-2=0

Can someone please explain to me how to find the interquartile range of something?
Alika [10]
I’ll do an example you have the numbers 1,5,7,2,9 you can tell the median is 7 right? So go from the very left and the median (7) and do the same thing you do to find median. (Id recommend crossing the numbers off as you go if that makes sense! :)
