Quadratic Equations - Finding the Coordinate of The Vertex

Hello,

 

I am given  `y=5x^2-10x+7` and I must change it to the form of 

`y=a(x-h)^2+k` . So I've already done this and the answer is `5(x-1)^2+2` 

For the coordinates I wrote -1,2 but the answer is 1,2. I don't understand this and how do you get the vertex coordinate? what do I need to look for? 


Thanks,

There are two reasons for converting a quadratic function from standard form `y=ax^2+bx+c` to vertex form `y=a(x-h)^2+k` .  Either you are trying to solve for x for a specific y-value (usually zero) or you are trying to find the vertex of the parabola (either to help...
