A real numbers are numbers that can be found on a number line, they include both rational and irrational numbers.
We can first solve the equation;
x² - 6x + 9 =0, using completing square method;
 x²- 6x + (-3)² = -9 + (-3)²
     (x-3)² = 0
       x = 3
therefore,  both values of x are 3, thus the expression has no real number x is negative.
        
                    
             
        
        
        
Answer:
94
Step-by-step explanation:
Do parentheses first, exponents inside them first. 4^2 = 16, + 1 is 17, then multiply by the 3 outside to get 51, then multiply by the 2 outside that to get 102, - 2^3 which is -8 = 94
