Use the discriminant to describe the roots of each equation. Then select the best description.
Marrrta [24]
Let's find the discriminant of <span>x^2+9x+14=0.  Here, a=1, b=9 and c=14.

The discriminant is b^2-4ac.  Substituting the above numeric values,
                                9^2-4(1)(14) = 81-56 = 25

The sqrt of 25 is 5.  Thus, your polynomial has two unequal, real roots.

Off the point example:  If the discriminant were zero, your poly would have two real, equal roots.</span>

Can someone please check to see if this is correct?..thanks <br> explanation would be appreciated
forsale [732]

2. Write the equation of the circle in general form
Anon25 [30]
(-1,-2) and (-1,4)
so these have same x values, but different y values, so these are on differnt sidef of circle

distanc between them is 6
6/2=3
radius=3

so move 3 units up from (-1,-2)
(-1,1)
so

if center is (h,k) and radius is r then
(x-h)^2+(y-k)^2=r^2

(-1,1) is center and r=3

(x-(-1))^2+(y-1)^2=3^2
(x+1)^2+(y-1)^2=9
