In elementary algebra, completing the square is a technique for converting a quadratic polynomial of the form + + to the form + for some values of and . [1] In terms of a new quantity x − h {\displaystyle x-h} , this expression is a quadratic polynomial with no linear term.

This is also an application of completing the square, allowing us to write a quadratic polyomial of three variables in which all terms have degree two, as the sum of three squares. (My inspiration was a multivariate calculus problem: Create a tranformation to map the ellipsoid x 2 + 4 x y + 8 y 2 + 4 y z + 6 z 2 − 2 x z = 9 , {\displaystyle x ...
The missing square puzzle is an optical illusion used in mathematics classes to help students reason about geometrical figures; or rather to teach them not to reason using figures, but to use only textual descriptions and the axioms of geometry. It depicts two arrangements made of similar shapes in slightly different configurations.
The numbers are based on a $50 a square game, with a $625 payout for the 1st and 3rd quarters, a $1,250 payout for halftime, and a $2,500 payout for the end of the game. (The cells are colored ...

A correct answer scored one point and claimed the square, but a miss gave the point and the square to the opponent. As before, contestants scored five bonus points for completing a 4 Square. Some squares (either four or seven) hid sad faces, called "gremlins" by the host. If a contestant found a gremlin, the opponent earned the square and the ...
