#### Explanation:
It is done by splitting the middle terms such the coefficients ad up to -12 and their product is +12.
In the present case -7x can be split as -3x and -4x. The multiplication of coefficients also gives +12. Accordingly,

$\dfrac { 5+2i }{ 1-i } +\dfrac { 5-2i }{ 1+i }$
#### Solution
$\dfrac { 5+2i }{ 1-i } +\dfrac { 5-2i }{ 1+i } =a+ib$
$\Rightarrow \dfrac { 5+5i+2i-2+5-5i-2i-2 }{ 1+1 } =a+ib$
$\Rightarrow \dfrac{6}{2}=a+bi$
$\Rightarrow 3=a+bi$
$\Rightarrow a=3,$ $b=0$

## regress, probit, or logit?
In a previous post I illustrated that the probit model and the logit model produce statistically equivalent estimates of marginal effects. In this post, I compare the marginal effect estimates from a linear probability model (linear regression) with... | {} |

Solving for y
How is y solved for in this equation?
$x=\frac{1-\sqrt{y}}{1+\sqrt{y}}$

Multiply both sides of the equation by $1/(1 + \sqrt{y})$, then isolate $\sqrt{y}$. The rest will follow.

I've got a question here which I'm really unsure what the wording is asking me to do, I've calculated (5), so worked out the steady states. However question 6 has really thrown me off with it's wording, any help would be appreciated.

In general relativity, the sticky bead argument is a simple thought experiment designed to show that gravitational radiation is indeed predicted by general relativity, and can have physical effects. These claims were not widely accepted prior to about 1955, but after the introduction of the bead argument, any remaining... | {} |

# CreateInstance and DeleteInstance¶
The creation of a CIM instance and in turn the creation of the underlying managed resource is achieved by calling the CreateInstance() method. It takes a pywbem.CIMInstance object as input, which specifies the class and the initial properties for the CIM instance to be created, and... | {} |

# Bounding the difference of numbers between 0 and 1 with the same power
I would like to prove the following inequality (I guess it holds but I'm not able to formally do it). Consider two numbers $$x,y\in (0,1)$$ and the positive real number $$\alpha$$. Then, can I write $$|(1-x)^\alpha-(1-y)^\alpha|\leq c \cdot |x-y|... | {} |

Is there an intuitive argument for the correct bounds of a confidence interval in a one-sided hypothesis test?
Assume I have a hypothesis
$$H_0: \mu \leq 0$$ $$H_1: \mu > 0$$
which corresponds to R's alternativ "greater" and which I would like to check with a confidence level of $$95\%$$ ($$\alpha = 0.05$$). I thoug... | {} |

# Heat of Sublimation
The heat (or enthalpy) of sublimation is the amount of energy that must be added to a solid at constant pressure in order to turn it directly into a gas (without passing through the liquid phase).
