who is good at completing squares? i need one on one help

Question

anonymous · Answer

$$x^2+6x=1=0$$
$$x^2+6x=-1$$
$$(x+3)^2=-1+3^3=8$$
$$x+3=\pm\sqrt{8}$$
$$x=-3\pm\sqrt{8}$$ is an example of solving a quadratic using that method

amistre64 · Answer

completeing a square is intuitively a geometric concept:

x^2 + 6x + ______
\begin{array}c
x^2&x&x&x\
x&1&2&3\
x&4&5&6\
x&7&8&9\
\end{array}
x^2 + 6x + "9" is a complete square

this concept gets us to the algebraic method;  take the number of "x"s that are added on and divide them in half

6/2 = 3

now we square that value to determine how to "complete" our square:

3^2 = 9
