And the quadratic sparse polynomial is increased to thick polynomial, so that the scale of the polynomial functions equivalent to the public key is exploded.

Euler discovered the remarkable quadratic formula:

There, we considered the function for computing the roots of a quadratic polynomial:

The symmetry between x and y is enforced by the quadratic polynomial x2+y2, which is rotation symmetrical in contrast to the monomial xy.

The quadratic surds (irrational roots of a quadratic polynomial ax2 + bx + c with integer coefficients a, b, and c) are algebraic numbers.

The Frobenius endomorphism satisfies a quadratic polynomial which is linked to the cardinality of E ( F q ) by the following theorem:

The Frobenius endomorphism satisfies a quadratic polynomial which is linked to the cardinality of E ( F q ) {\displaystyle E(\mathbb {F} _{q})} by the following theorem:

The quadratic surds (irrational roots of a quadratic polynomial ax^2 + bx + c with integer coefficients a, b, and c) are algebraic numbers.

In [10] the best approximation to 1/(1 + x) on [0, 1] by a quadratic polynomial is given as an example of how Zolotarev's methods can be used.

Find the product of the coefficients, a and b, for the quadratic expression that produces the maximum number of primes for consecutive values of n, starting with n = 0.
