HELP

 

what is y=x2−2 and y=−x+4 solutions  

 

y = y so you can set the equivalents equal 

 

                                                    x² – 2 = x + 4 

 

subtract x + 4 from both sides      x² – x – 6 = 0   

 

factor the quadratic                      (x + 2)(x – 3) = 0 

 

                                                     x = –2  and  x = 3

Darn it, I missed a sign when I started the answer. 

 

It should be:  

 

y = y so you can set the equivalents equal 

 

                                                       x² – 2  =  –x + 4 

 

subtract  –x + 4 from both sides      x² + x – 6  =  0   

 

factor the quadratic                         (x – 2)(x + 3)  =  0 

 

                                                        x = +2  and  x = –3
