Completing the Square

When solving by completing the square, what would be the first step?

 $x^2=11-6x$  

• Set the equation equal to zero 

• Divide the -6 by 2 and square it

• Move the -6x to the other side, put "x" terms together on one side

• Find factors of 11 that add to 6

Solve the equation

 $x^2+4x+5=0$  

•  $x=\left\{-1,\ -5\right\}$  

•  $x=2\pm i$  

•  $x=-2\pm i$  

•  $x=-2\pm3i$  

Solve by completing the square:
k² − 12k + 23 = 0

• {6 + √13, 6 - √13}
• {-6 + √13, -6 - √13}
• {6 + √59, 6 - √59}
• {-6 + √59, -6 - √59}

Solve by completing the square. Round.
x² -4x = 5

• 11 and -7
• 1 and 3
• 1.73 and -1.73
• 5 and -1

Solve by completing the square.
x² +12x = 5

• X = 6 + √41 or  6 − √41
• X= 35 or 47
• X = −6 + √41 or  −6 − √41
• X = √35 or √47

Solve by completing the square.
 $x^2-12x+20=0$  

•  $x=\left\{2,\ 10\right\}$  

•  $x=\left\{-10,\ -2\right\}$  

•  $x=\left\{-12,\ 20\right\}$  

•  $x=\left\{12,\ 20\right\}$  

Solve by completing the square.
 $x^2-4x-20=0$  

•  $x=\left\{\pm6\sqrt{2}-2\right\}$  

•  $x=\left\{\pm6\sqrt{2}+2\right\}$  

•  $x=\left\{\pm2\sqrt{6}+2\right\}$  

•  $x=\left\{\pm2\sqrt{6}-2\right\}$  

Solve by completing the square.
 $x^2-6x-59=0$  

•  $x=\left\{\pm2\sqrt{17}+3\right\}$  

•  $x=\left\{\pm17\sqrt{2}+3\right\}$  

•  $x=\left\{\pm2\sqrt{17}-3\right\}$  

•  $x=\left\{\pm17\sqrt{2}-3\right\}$  

Solve by completing the square.
 $x^2-16x+48=0$  

•  $x=\left\{-12,\ 4\right\}$  

•  $x=\left\{-12,\ -4\right\}$  

•  $x=\left\{-4,\ 12\right\}$  

•  $x=\left\{4,\ 12\right\}$  

Solve by completing the square.
 $x^2-4x-21=0$  

•  $x=\left\{-7,\ 3\right\}$  

•  $x=\left\{3,\ 7\right\}$  

•  $x=\left\{-3,\ 7\right\}$  

•  $x=\left\{-7,\ -3\right\}$
