how to find the points of intersection for the curves y=x^2 and y=x+2
i know they are (-1,1) AND (2,4) BUT HOW DO U GET THIS?

x^2 = x+2
x^2-x-2=0
Solve it using quadratic formula for least headache
x = 2,-1
Clearly do you not know how to get this.

frm the two relatio we get
x^2=x+2
or x^2-x-2=0
then use the following equation
x=(-b+-root(b^2-4ac))/2a
x^2=x+2
or x^2-x-2=0
then use the following equation
x=(-b+-root(b^2-4ac))/2a
