Write the quadratic equation in general form. (x - 3)^ 2 = 0
algol [13]
The answer is:  x² – 6x + 9 = 0  .
_____________________________________________________
Explanation:
________________________________________________________

Given:  (x – 3)² = 0 ;  write as: general form:  "ax² + bx + c = 0";  a ≠ 0 .
<span>
Note:  </span>(x – 3)² = (x – 3)(x – 3) = x² – 3x – 3x + 9 = x² – 6x + 9 ;
___________________________________________________
Rewrite: (x – 3)²  =  0 ;  →
           as:   x² – 6x + 9 = 0  ; which is our answer.
____________________________________________
→   x² – 6x + 9 = 0  ; is in "general form", or "standard equation format"; that is: " ax² + bx + c = 0 ";  (a ≠ 0) ;
             → in which: 
   a =  1 (implied coefficient, since anything multiplied by "1" is that same                                                                                                                    value);
   b = -6; 
   c =  9

12)<br> Which graph represents the solution for the equation-x-1=-x+ 2?
antiseptic1488 [7]

Answer:

Find the graph that has (2,0)

Step-by-step explanation:

\frac{1}{2}x -1=-x+2

+ x          +x

\frac{3}{2}x - 1  = 2

2(\frac{3}{2}x - 1  = 2)

3x - 2 = 4

    + 2   + 2

3x = 6

/3   /3

x = 2

Your image is blurry, but the point that has (2,0)

Hope that helps!
