Answer:
The answer to your question is:       (2a + 2b)²
Step-by-step explanation:
a² + b² = z
ab = y
Which is equivalent to 4z + 8y ?
Substitution 
                                      4(a² + b²) + 8(ab) 
Simplify                        4a² + 4b² + 8ab
Order                            4a² + 8ab + 4b²       It's a perfect square trynomial
Factorize                     (2a + 2b)²
 
        
                    
             
        
        
        
The answer is R= {-7, 1, 9, 17}. All you have to do is plug in the numbers (the domain) into the equation.
