What number should be added to both sides of the equation to complete the square x^2+3x=6
Allisa [31]
Take half of the coefficient of x:  It is 3, and half that is 3/2.


Then   <span>x^2+3x=6  becomes:

</span><span>           x^2+3x + (3/2)^2 =6 + (3/2)^2, and

             (x+3/2)^2 = 6 + 9/4

You were not asked to solve the equation, but why not do it for the practice?

</span>Solve (x+3/2)^2 = 6 + 9/4 for x.  There will be 2 values.

Drag each expression to show whether it is equivalent to 54x plus 18, 18(3x minus 1), or (6 times 9x) plus (6 times 1)
topjm [15]

The first option is

18(3x-1) = 18\cdot 3x - 18\cdot 1 = 54x-18

The second option is

6\cdot 9x + 6\cdot 1 = 54x + 6

So, neither of them is equivalent to 54x+18
