f the equations are accordinglyx = 2, y = ± 2, and the correspondingcurves intersect at the points (2, 2)and (2, - 2) (fig. 42). From the figure it is also evidentthat the value — 4 for x must make yimaginary, as both curves lie entirelyto the right of the line x = — 4. Ex. 8. Find the points of… … V-3 Fig. 42 Substituting these values of x in (1), we find the corresponding values of y to be 0, :>. and 3T3V- :$ Therefore the real solutions of the ationa are x = 0, y = 0 and x= 3, y= ■>. If we hadsubstituted the values of x in (2), we should have at first seemed tofind an additional real…
