Add powers of 3.
1 + 3 = 4
4 + 9 = 13 = 4 + 3^2
13 + 27 = 40 = 13 + 3^3
40 + 81 = 121 = 40 + 3^4
Now you need to add 3^5 to 121.
121 + 3^5 = 121 + 243 = 364

The number which could be added to both sides of the equation to complete the square is; -2.25.
<h3>Which number could be added to both sides of this quadratic equation to complete the square?</h3>
The quadratic equations give in the task content is; 1=x²-3x. Hence, to express the equation by completing the square method; we have;
1 - 2.25 = (x -3/2)² - 2.25
Hence, the number which should be added to both sides of the equation is; -2.25.
