What is the vertex of #y=x^2-2x-35#?
I have shown a really 'cool' trick to solve this.
To demonstrate how useful the method I am about to show you is.
Just by looking at the given equation I determine that
Then it is just a matter of substitution to find
Ok! lets deal with the method!
The standardised equation structure
In you case
Sometimes the number are a bit more difficult to work out.
