Difficulty level:  

Worksheet Overview

This worksheet is about calculating the intersection of quadratic and linear functions.

 

Example

Use the graphs of y=x2+2x-3  and y=6 to solve x2+2x-3=6

You should get two answers each time (in this example x1=-4.2, x2=2.2).

This is the solution to the pair of simultaneous equations:
y = x2 + 2x - 3
y = 6
