- Learning Task 2 Find Me! Transform the given quadratic function y=ax2+bx+c into standard form y=a(x-h)2 + k and fina the vertex. 1. y = x2 - 2x - 15 2. y= 2x2 - 4x 3. y = x2 - 2x - 3 4. y = x2-x+ 5. y = 3x - 12x + 2 - I​

with: y=ax2+bx+c

We want to put it into vertex form: y=a(x-h)2+k

We can convert to vertex form by completing the square on the right hand side

36 is the value for 'c' that we found to make the right hand side a perfect square trinomial

Our perfect square trinomial factors into two identical binomials, (x+6)•(x+6)

The vertex of an equation in vertex form is (h,k), which for our equation is (-6,-4)
