Two parabolas are the graphs of the equations y=2x^2-10x-10 and y=x^2-4x-8. Find all points where they intersect. List the points in order of increasing x-coordinate, separated by semicolons.
Equate the two equations then solv for 'x' using the quadratic formula to find the two
x coordinates of the two points of intersection
x = 3 +- sqrt 11 use these values in either of the equation to calculate the corresponding y coordinate of the points of intersection.
