Pells equation Type of Diophantine equation

Pell's equation, also called the Pell–Fermat equation, is any Diophantine equation of the form where n is a given positive nonsquare integer and integer solutions are sought for x and y. In Cartesian coordinates, the equation is represented by a hyperbola; solutions occur wherever the curve passes through a point whose x and y coordinates are both integers, such as the trivial solution with x = 1 and y = 0. Joseph Louis Lagrange proved that, as long as n is not a perfect square, Pell's equation has infinitely many distinct integer solutions. These solutions may be used to accurately approximate the square root of n by rational numbers of the form x/y.

A Pell Grant is a subsidy the U.S. federal government provides for students who need it to pay for college. Federal Pell Grants are limited to students with financial need, who have not earned their first bachelor's degree, or who are enrolled in certain post-baccalaureate programs, through participating institutions. Originally known as a Basic Educational Opportunity Grant, it was renamed in 1980 in honor of Democratic U.S. Senator Claiborne Pell of Rhode Island. A Pell Grant is generally considered the foundation of a student's financial aid package, to which other forms of aid are added. The Federal Pell Grant program is administered by the United States Department of Education, which determines the student's financial need and through it, the student's Pell eligibility. The U.S. Department of Education uses a standard formula to evaluate financial information reported on the Free Application for Federal Student Aid (FAFSA) for determining the student's Expected Family Contribution (EFC).
