Question 945378: Use substitution to find where the two parabolas below intersect. Then confirm your solution by graphing both on the same set of axes.
y=x^2+5
y=x^2+2x+1

Subtract x^2 from each side
Subtract 1 from each side
Divide each side by two

Substitute in the two original equations and find y







So the two graphs intersect at the point (2,9)
