How do you write a quadratic form?

An equation that is quadratic in form can be written in the form au2+bu+c=0 where u represents an algebraic expression. In each example, doubling the exponent of the middle term equals the exponent on the leading term.

What is quadratic standard form?

The quadratic function f(x) = a(x - h)2 + k, a not equal to zero, is said to be in standard form. If a is positive, the graph opens upward, and if a is negative, then it opens downward. The line of symmetry is the vertical line x = h, and the vertex is the point (h,k).
