X4 4x2 32 0 x22 4x2 32 0 u2 4u 32 0. The matrix Ais called the matrix of the quadratic form. They tend to look like a smile or a frown.
Since u x2 we can back substitute and then solve for x.
This type of relation is represented by a parabola on a graph. They tend to look like a smile or a frown. If a 0 then the equation is linear not quadratic as there is no ax² term. The degree of the equation 2 the exponent on x makes the equation quadratic.
