Get into form y=a(x-h)²+k where (h,k) is vertex
some terms:
quadratic coefient: number in front of the x² term
linear coefient: number in front of the x term
basically complete the square
so
y=x²+ax
first factor out the quadratic coefient (1),
y=1(x²+ax)
take 1/2 of the linear coefient and square it
,
add positive and negative of it inside the parentesees
factor perfect square
distribute
so invertex form, it is
or
the vertex is
