To solve this equation using the completing the square method, we rearrange the equation so that the constant term is isolated on one side:
x + 2x + 8 = 0
Combine like terms: 3x + 8 = 0
Subtract 8 from both sides: 3x = -8
Next, we divide both sides by the coefficient of x, which is 3:
3x/3 = -8/3
x = -8/3
Therefore, the solution to the equation x + 2x + 8 = 0 using the completing the square method is x = -8/3.
Using completing the square method solve for x in the following
X+2x+8=0
