Using completing the square method solve for x in the following

Question

X+2x+8=0

Answer 1

To solve for x using the completing the square method, we want to rewrite the equation in the form (x + a)^2 = c, where a and c are constants.

Given: x + 2x + 8 = 0

Step 1: Group the x terms together:
3x + 8 = 0

Step 2: Move the constant term to the other side of the equation:
3x = -8

Step 3: Divide both sides by the coefficient of x to isolate the x term:
x = -8/3

Thus, the solution for x using the completing the square method is x = -8/3.
