# Rigid category
In category theory, a branch of mathematics, a rigid category is a monoidal category where every object is rigid, that is, has a dual X* (the internal Hom [X, 1]) and a morphism 1 X X* satisfying natural conditions. The category is called right rigid or left rigid according to whether it has right dua... | {} |

# How can you solve x^2 – 4x – 5 = 0 by using the quadratic formula and by factoring?
Oct 21, 2015
Solve x^2 - 4x - 5 = 0
Ans: -1 and 5
#### Explanation:
y = x^2 - 4x - 5 = 0
Since (a - b + c = 0), use Shortcut. The 2 real roots are: - 1 and (-c/a = 5) | {} |

A natural mechanism for approximate Higgs alignment in the 2HDM
A bstract The 2HDM possesses a neutral scalar interaction eigenstate whose tree-level properties coincide with the Standard Model (SM) Higgs boson. In light of the LHC Higgs data which suggests that the observed Higgs boson is SM-like, it follows that the ... | {} |
