... (x − 5)(x + 2) is the factored form of x − 3x − 10. So, the statement is false. 4. Expressions with four or more unlike terms can sometimes be factored by grouping. SOLUTION: Using the Distributive Property to factor polynomials with four or more terms is called factoring by grouping because terms ...

... x: dogs in the shelter y: cats in the shelter Step 2: Write a system of equations. The total number of animals in the shelter is 40, so we know x + y = 40. Because there are 10 more dogs than cats, we also know that x – y = 10. x + y = 40 x – y = 10 Copyright © 2009 Pearson Education, Inc. Publishin ...

BKL singularity
A BKL (Belinsky–Khalatnikov–Lifshitz) singularity is a model of the dynamic evolution of the Universe near the initial singularity, described by an anisotropic, homogeneous, chaotic solution to Einstein's field equations of gravitation. According to this model, the Universe is oscillating (expanding and contracting) around a singular point (singularity) in which time and space become equal to zero. This singularity is physically real in the sense that it is a necessary property of the solution, and will appear also in the exact solution of those equations. The singularity is not artificially created by the assumptions and simplifications made by the other well-known special solutions such as the Friedmann–Lemaître–Robertson–Walker, quasi-isotropic, and Kasner solutions.The Mixmaster universe is a solution to general relativity that exhibits properties similar to those discussed by BKL.
