Solve for x: √(2X+8)-4=2
add 4 to both sides, then square both sides.
¡Ì(2X+8)=6
then,(2X+8)=36
next,2X=28
at last, X=14
To solve for x in the equation √(2x+8)-4=2, you can follow these steps:
Step 1: Isolate the square root term by adding 4 to both sides of the equation:
√(2x+8) = 6
Step 2: Square both sides of the equation to eliminate the square root on the left side:
(√(2x+8))^2 = 6^2
2x + 8 = 36
Step 3: Subtract 8 from both sides of the equation:
2x = 36 - 8
2x = 28
Step 4: Divide both sides of the equation by 2 to solve for x:
x = 28/2
x = 14
So, the solution to the equation is x = 14.
