Luke has taught high school algebra and geometry, college calculus, and has a master's degree in education. A quadratic equation is an equation of the form f(x)=ax2+bx+c. Completing the square is a method by which the solutions or roots of any quadratic equation can be found. The met...
The square of a trinomialCompleting the square Geometrical algebra Problem 7. Without multiplying outa) explain why (1 − x)2 = (x − 1)2.Because (1 − x) is the negative of (x − 1). And (−a)2 = a2 for any quantity a....
Working with quadratic equations is just one element of algebra you’ll need to master before taking the SAT and ACT. A good place to start is mastering systems of equations, which will help you brush up on your fundamental algebra skills, too. One of the most helpful math study tools is...
1) Transpose the constant term to the rightx2 + 6x = −2.2) Add a square number to both sides: Add the square of half the coefficient of x. In this case, add the square of 3:x2 + 6x + 9 = −2 + 9.The left-hand side is now the perfect square of (x + 3). ...

We determine the Hochschild cohomology algebras of the square-free monomial complete intersections. In particular we provide an explicit formula for the cup product which gives the cohomology module an algebra structure and then we describe this structure in terms of generators and relations. In ...
