Given the complex number Z = (1-I) 2 + 1 + 3I, if Z2 + AZ + B = 1-I, a, B ∈ R, then the value of real number pair (a, b) is______ .
∵ complex z = (1-I) 2 + 1 + 3I = 1 + I, Z2 + AZ + B = 1-I, ∵ a + B + (a + 2) I = 1-I, ∵ a + B = 1, a + 2 = - 1, ∵ a = - 3, B = 4, so the answer is (- 3, 4)
The singular and plural of English nouns
My parents seldom permit me to go out at night,so I should ask them for their permisson first.
Can I use permissions in a sentence
Permission. Is both countable and uncountable
As a countable noun, it means: license; written permission
This can be in the plural, such as oil exploration permissions
As an uncountable noun, it is permission, permission and approval;
There is no plural. As you have written
Can you add the plural after "such"?
Sometimes it can be like this
Before the corresponding limit of the such, refers to the previously mentioned a kind
He noticed her necklaces. Such jewels must have cost though, he thought
Description: it is known that the complex Z satisfies Z-4 = (3-2z) I 1. Find the complex Z 2. If Z + W and (Z + 1) W are both real numbers, find a quadratic equation with real coefficient and one root of W
Because Z-4 = (3-2z) I, so Z-4 = 3i-2zi, then (1 + 2I) z = 4 + 3I, then z = (4 + 3I) / (1 + 2I) = 2-I, let w = a + bi, Z + W = (a + 2) + (B-1) I (Z + 1) w = (3-I) (a + bi) = (3a + b) + (3b-a) I, because Z + W and (Z + 1) W are real numbers, so B-1 = 0, 3b-a = 0, a = 3, B = 1, w = 3 + I and W is one of them
1. Because Z-4 = (3-2z) I
So Z-4 = 3i-2zi
(1+2i)z=4+3i
z=(4+3i)/(1+2i)
=2-i
2. Let w = a + bi, then
z+w=(a+2)+(b-1)i
(z+1)w=(3-i)(a+bi)
=(3a+b)+(3b-a)i
If Z + W and (Z + 1) W are both real numbers
So B-1 = 0, 3b-a = 0
The singular and plural in English
I love my dog or I love my dogs?
I love my dog. Or I love my dogs
The difference lies in that the former is a dog and the latter is more than two dogs. The choice of sentence depends on the actual situation or the clues given in the article
I love my dog
It depends on how many dogs you have,
If there's only one, it's I love my dog
If there are more than two, I love my dogs

Can that refer to a plural noun?
He bought two tickets to Lon and told her he put___ into her handbag.
A.it B.them C.this D.that
Why can't b? But I think D. that should be that?
They are the accusative case of the two tickets
If you use that, you need to add tickets after that
