Given the equation:
Let's solve the equation for x.
Square both sides:
Solving further:
Expand using the FOIL method.
Apply distributigve property:
Move all terms to the left and equate to zero:
Factor the left side of the equation:
Equate each factor to zero and solve for x.
x - 3 = 0
Add 3 to both sides:
x - 3 + 3 = 0 + 3
x = 3
x - 1 = 0
Add 1 to both sides:
x - 1 + 1 = 0 + 1
x = 1
Hence, we have:
x = 3 and 1
Now, let's exclude the solution that do not make the equation true.
Input 3 for x in the equation:
The value of 3 makes the equation true.
Input 1 for x in the equation and evaluate:
The value of 1 do NOT make the equation true.
Therefore, the correct solution for x in the equation is 3.
ANSWER:
x = 3
