Note how both of these are equal to "y" y = x^2  5x + 4 y = 2x  2 or x^2  5x + 4 = y = 2x  2 now just "take out the middle man" (the y) and solve x^2  5x + 4 = 2x  2 Can you do this?

First step is to move all the variables to one side of the equal sign.

x^2  5x + 4 = 2x  2 add 2 to both sides x^2  5x + 6 = 2x subtract 2x from both sides x^2  7x + 6 = 0 See if you can factor the left side (if not, use quadratic formula)
