Factored to Standard: When your given the expression (x+2) (x+2) +0, how you would convert to standard form you would bring down down the +0 and multiply 2x2 which=4 and carry it down with the "+0". Then you have the two X's, which is X^2.
Standard to Factored: Standard to factored, you un-factor the equation. You take x^2+25+0 and turn 25 into a number when multiplied together will=25. In this problem, it's 5, and your equation looks like (x+5) (x+5).

Vertex to Standard: you take the equation (x+2)^2 and break it down (x+2) twice since thats what "^2" is. Then you bring down the "+0" and then multiply 2x2 which=4 and bring it down with the "+0". Your left two X's, which turns to X^2.
Standard to Vertex: getting from standard form to vertex form you have to solve the equation. You turn x^2+25+0 to (x+5) into (x+5)+0, then simplify the problem to (x+5)^2 +0
