Respuesta :

All three of the steps shown are correct. Finish the solution by solving

0 = (x+1)(x+3). The solutions are x= -1 and x = -3.


Now subst. -3 for x in either of the given equations, to find the corresponding y.


Next, subst. -1 for x in either of the given equations, to find the corresponding y.
