In terms of a new quantity , this expression is a quadratic polynomial with no linear term. By subsequently isolating ( x − h ) 2 {\displaystyle \textstyle (x-h)^{2}} and taking the square root , a quadratic problem can be reduced to a linear problem.
The quadratic equation on a number can be solved using the well-known quadratic formula, which can be derived by completing the square. That formula always gives the roots of the quadratic equation, but the solutions are expressed in a form that often involves a quadratic irrational number, which is an algebraic fraction that can be evaluated ...
In algebra, the partial fraction decomposition or partial fraction expansion of a rational fraction (that is, a fraction such that the numerator and the denominator are both polynomials) is an operation that consists of expressing the fraction as a sum of a polynomial (possibly zero) and one or several fractions with a simpler denominator.
The roots of the quadratic function y = 1 / 2 x 2 − 3x + 5 / 2 are the places where the graph intersects the x-axis, the values x = 1 and x = 5. They can be found via the quadratic formula. In elementary algebra, the quadratic formula is a closed-form expression describing the solutions of a quadratic equation.
President Joe Biden on Tuesday enacted the first federal anti-hazing law, marking the end of a yearslong push by victims' families for more transparency and accountability on college campuses. The ...

PARIS (Reuters) -The word "Merci" was projected on to the front of Paris' Notre-Dame cathedral as it reopened on Saturday, in thanks for its salvation after a devastating fire that brought the 860 ...
In mathematics, an expansion of a product of sums expresses it as a sum of products by using the fact that multiplication distributes over addition. Expansion of a polynomial expression can be obtained by repeatedly replacing subexpressions that multiply two other subexpressions, at least one of which is an addition, by the equivalent sum of products, continuing until the expression becomes a ...
