What number should be added to both sides of the equation to complete the square? x2 – 6x = 5
choli [55]

Answer: Add 9 to both sides to complete the square

Step-by-step explanation:

The formula for the number you need to add to complete the square is (b/2)^2. In this case, b = -6, so:

(b/2)^2 = (-6/2)^2 = (-3)^2 = 9.

(After adding 9 to both sides, you will get x^2 - 6x + 9 = 14 which can be factored to (x - 3)^2 = 14)

Now.. on the first one \bf \sqrt{-27}\cdot \sqrt{-3}\impliedby \textit{first, you convert them to "i" form}
\\\\\\
\sqrt{3^2\cdot 3\cdot -1}\cdot \sqrt{3\cdot -1}\implies \sqrt{3^2}\cdot \sqrt{3}\cdot \sqrt{-1}\cdot \sqrt{3}\cdot \sqrt{-1}
\\\\\\
3\sqrt{3}\ i\cdot \sqrt{3}\ i\implies 3(\sqrt{3})^2\ i^2\implies 3\cdot 3\cdot i^2\impliedby recall\quad i^2=-1
\\\\\\
-9\implies -9+0i
