You may recognize this as a quadratic function; a parabola is a graphic depiction of a quadratic function. In the equation above, a, b and c are constants, and a is not equal to zero. (If a were zero, ...

Negative four is less than or equal to x, less than or equal to two., Draw the graph of the quadratic equation 𝒚 = 𝒙² + 2𝒙 – 3 for values of 𝒙 from -4 to 2.

In this paper we present some results connected with still open problem of Gauss, negative Pell’s equation and some type graphs.In particular we prove in the Theorem 1 that all real quadratic fields ...

We give asymptotic upper and lower bounds for the number of squarefree d (0 < d ≤ X) such that the equation x² − dy² = −1 is solvable. These estimates, as usual, can equivalently be interpreted in ...
