The line y=5-x intersects the curve y=x^2-3x+2 at the points P and Q. Find the (x,y) coordinates of P and Q.

Step 1: To find the points of intersection, we must find where the y and x values are equal. Therefore 5-x=x 2 -3x+2 where the y-values are equal. Step 2: Rearrange the above into the quadratic equation x 2 ...
