Two parabolas are the graphs of the equations y = 2x^2 - 10x - 10  and y = x^2 - 7x - 12. Give all points where they intersect. List the points in order of increasing x-coordinate, separated by semicolons.

Set the two equations equal..... simplify so all of the terms are on one side of the = sign and '0' is on the other.,,

  Use Quadratic Formula to solve for 'x' s     use these values of x in oneof the equations to solve for the corresponding y's

 

Here is a graph you can use to verify your work:
