what equation results from completing the square and then factoring? x^2+4x=5

Completing the square - Vertex is (-5/4, 11/16) Quadratic Formula (-5/4, 11/8) This is what I got when I used both of the formulas. I am pretty sure that you are supposed to...

How do you solve this problem by completing the square? x^2+6x=9

I need to complete the square.

I have the problem of x(squared)+2x=9. I understand completing the square to a degree, but I don't know how it works with a 2 in the x spot.

Rewrite the quadratic function in standard form by completing the square f(x)= -1/4x^2+5x-2

f(x)=-3x2-2+1 I tried it and I got (-3x2-2x+1)-6 after completing the square, then I factored it and got (-3x+1)(x+1)-6 , if I did it correctly how am I supposed to get a vertex...
