Hi,

How to express the quadratic functions in the form of F%28x%29=a%28x%2Bk%29%5E2+%2Bh+

By completing the Square..y = ax^2 + bx + c   ⇒ y+=+a%28x+-%28-b%2F2a%29%5E2%29+-+a%28-b%2F2a%29%5E2+%2B+c

F(x) = 5x^2 + 7x + 2

F%28x%29+=+5%28x+%2B+7%2F10%29%5E2+-+49%2F20+%2B+40%2F20

F%28x%29+=+5%28x+%2B+7%2F10%29%5E2+-+9%2F20
