Answer:

1 would complete the square

Step-by-step explanation:

In order to solve this you have to remember the formlua for the perfect quadratic trinomial:

[tex]a^2 + 2 ab +b^2=0[/tex]

IN the example you have A^2 and 2ab, since A=1, then the 2x will resulto from the multiplication of b and a multiplied by 2, so we just have to divide 2x by 2x to get b:

[tex]\frac{2x}{2x}=1[/tex]

So we get that b is 1.
