Using completing the square method solve for x in the following
X+2x+8=0
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.
To solve the quadratic equation x + 2x + 8 = 0 using the completing the square method, follow these steps:
Step 1: Move the constant term to the other side of the equation:
x + 2x = -8
Step 2: Combine like terms:
3x = -8
Step 3: Divide both sides of the equation by the coefficient of x to isolate the variable:
x = -8/3
So, the solution to the quadratic equation x + 2x + 8 = 0 is x = -8/3.
To solve the quadratic equation x + 2x + 8 = 0 using the completing the square method, we follow these steps:
Step 1: Group the x terms together:
x + 2x + 8 = 0
Combine like terms:
3x + 8 = 0
Step 2: Move the constant term (8 in this case) to the other side of the equation:
3x = -8
Step 3: Divide through by the coefficient of x (3 in this case) to isolate x:
x = -8/3
Hence, the solution to the quadratic equation x + 2x + 8 = 0 is x = -8/3.
