Solve the equation by completing the square and then solving for x. 1. x^2-6x=12<br>2. 2x^2-24x=-20
Paraphin [41]

Answer:  (x - 3)² = 21

<u>Step-by-step explanation:</u>

x² - 6x + ____ = 12 + ____

       ↓        ↑                 ↑

    \frac{-6}{2} = (-3)^{2}

x² - 6x + <u> 9 </u> = 12 + <u> 9 </u>

       (x - 3)²  =    21

*******************************************************

Answer:  (x - 6)² = 26

<u>Step-by-step explanation:</u>

2x² - 24x = -20

<u>÷2 </u>   <u> ÷2  </u>    <u> ÷2 </u>

 x² -  12x =  -10

x² - 12x + ____ = -10 + ____

       ↓        ↑                   ↑

    \frac{-12}{2} = (-6)^{2}

x² - 12x + <u> 36 </u> = -10 + <u> 36 </u>

       (x - 6)²  =    26

Mystery number: The number is less than 190000 and greater than 180000.
Kipish [7]
The answer to it is    
180, 000 <n> 190, 000 
180,000 + 2000 = n = 5000-187, 000 
182,000 = n = 182, 000   
Or,  
 180, 000 <n> 190,000                     
 n + 5000= 187, 000                           n – 2000 = 180, 000 
 n= 187, 000- 5000                             n = 180, 000 + 2000 
 n= 182, 000                                       n= 182, 000
