The complete equation is x^2 - 4x + (-2) = (-2)^2
<h3>How to complete the equation?</h3>
The equation is given as:
x^2 - 4x + __ = (__)^2
_____________________________
Take the coefficient of x
k = -4
Divide by 2
k/2 = -4/2
k/2 = -2
Square both sides
(k/2)^2 = (-2)^2
_____________________________
Add the result of the above computation to both sides of x^2 - 4x + __ = (__)^2
So, we have:
x^2 - 4x + (-2) = (-2)^2
Hence, the complete equation is x^2 - 4x + (-2) = (-2)^2

Answer:
x = -2
Step-by-step explanation:
Multiply both sides by 3 to get rid of the fraction:
x - 10 = -12
Add 10 to both sides:
x = -2
