What is the vertex form of #y=-1/3(x-2)(2x+5) #?
The Vertex Form is
We start from the given
now, factor out the 2
complete the square now by adding
the first 3 terms inside the grouping symbol is now a Perfect Square Trinomial so that the equation becomes
let us simplify now to the Vertex Form
God bless...I hope the explanation is useful..
