Solve the following quadratic equation for all values of x in simplest form.
3(x + 8)2 – 20 = 28

The table below shows the height of a ball  x  seconds after being kicked.  what values, rounded to the nearest whole number, complete the quadratic regression equation that models the data? f(x)  =  x2  +  x  +  0based on the regression equation and rounded to the nearest whole number, what is the estimated height after 0.25 seconds?   feet

Select the sequences that are geometric.

If the discriminant if a quadratic equation is 4 which statement describes the roots?
