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
