Solve the quadratic equation using the square root property. 25=(x+8)^2  

 

Definition from online:  "the square root property states that if we have an equation with a perfect square on one side and a number on the other side, then we can take the square root of both sides and add a plus or minus sign to the side with the number and solve the equation"   

 

                                                                                 25  =  (x + 8)2    

 

Take the square root of both sides                             5  =  x + 8     

 

Add a plus or minus side to the number                   +5  =  x + 8    

 

Subtract 8 from both sides                                         x  =  (–3, –13)
