Fill in the missing term so that the quadratic equation has a graph that opens up, with a vertex of (– 3, – 25), and x intercepts at x = -8 and x = 2. (Do not include the negative sign in your answer.) y = x2 + 6x − ___

if the vertex is (-3,-25) you can write $-25=(-3)^2+6\times (3)+c$ and solve for c

OpenStudy (anonymous):

or you could write $0=(-8)^2+6\times (-8)+c$ and solve for c

OpenStudy (anonymous):

for that matter you can write $y=(x+8)(x-2)$ multiply out and find c. that may be easiest. $y=x^2+6x-16$

OpenStudy (anonymous):

in fact the very very simplest way to do it is take the zeros, -8 and 2, and multiply them together to get $c=-16$
