Answer:
completing the square is making the expression a bunch of perfect squares in order to solve it easily and find
Explanation:
If i have the expression x^2 + 4x + 1 = 0
i move the one to the right side
x^2+4x=-1
then i add b over 2 squared to both sides
that is x^2+4x+4=3
now i would simply take the square root of both sides of this equation,
(x+2)^2=positive or negative 1.73
x+2=-1.73
x+2=1.73
then you subtract or add to solve for both possible values of x
