Solve each equation by completing the square. n^2 - 6n + 6 = -2​
Law Incorporation [45]
<h3><u>Explanation</u></h3>
  • Separate the constant out of expression.

( {n}^{2}  - 6n) + 6 =  - 2

  • Find the constant that makes the expression able to be squared. You have to subtract the separated constant by new constant as well.

( {n}^{2}  - 6n + 9) + 6 - 9 =   - 2 \\  {(n - 3)}^{2}  - 3 =  - 2 \\  {(n - 3)}^{2}  = 1

  • Square Root both sides to get rid the squared expression. Make sure to write plus or minus.

\sqrt{ {(n - 3)}^{2} }  =   + \sqrt{1}  \\   \sqrt{ {(n -  3)}^{2} } =  -  \sqrt{1}  \\ n - 3 = 1 \\ n - 3 =  - 1

n - 3 = 1 \:  \:  \: or \:  \:  \: n - 3  =  - 1 \\ n = 1 + 3 \:  \:  \:  or \:  \:  \: n =  - 1 + 3 \\ n = 4 \:  \:  \: or \:  \:  \: n = 2

<h3><u>Answer</u></h3>
