Anonymous users2024-02-06Polynomial, for example: 0=x 5+x 3+9, coefficient is the coefficient: to the fifth power and to the third power x is preceded by 1
Simplify: 0=x*(x 2-3) 2 so x=0 or (x 2-3) 2=0
The first sentence: Let the solution above with the equation 0 be real or imaginary, but the imaginary numbers need to be in pairs.
Sentence 2: If the pleotropy of the solution of a real number is even, for example, (x 2-3) 2=0 and his multiplicity is 2 (the outermost percolation square), then the root x = positive and negative root numbers are three simple and fierce, and the drawing will only be next to the x-axis, but it will not be crossed.
The third sentence: the number of multiplicities = the number of all the real number root "0", or the example of a bridge (x 2-3) 2=(x 2-3)(x 2-3).
We have two (x 2-3)=0 so multiplicity =1+1=2

Hehe, when are you going to take the exam?

You can think of this pattern as a whole. (Contains 5 retangulars).
The length is 2L, and the width is 5L 3
To compose a 12l by 10l.
The long side is 6 (=12 2) times, and the wide side is 6 (=10 (5 3)) times, so you need 6*6=36 patterns
So it's a total of 36*5=180 retangulars

Anonymous users2024-02-01The meaning of this problem is to give you the value of the independent variable x and the corresponding value of the function f(x), and then say, there is a formula g(x)=f(3x+1), ask you what g(2) is equal to, and the solution: g(x)=f(3x+1).
g(2)=f(3*2+1), that is: g(2)=f(7) and then find the correspondence given above, when x=7, f(7)=-5, then g(2)=-5
If you don't understand, you can ask me

The most important one is, of course, to do the real questions, in which you can fully experience the focus and style of the vocabulary test in the SAT test, which is very instructive for memorizing words; Second, in the process of reading, you will encounter a large number of SAT words, these words sometimes do not affect reading, but in the early stage of exam preparation, many people do not know which words do not affect comprehension, which are crucial, so at this time you need to try to find as many relevant words as possible, and then you can slowly summarize the SAT words that are useful to you. In addition, you must memorize SAT words according to your actual situation, find the most suitable one for yourself in various methods, and then apply it, so that it can be more effective. Remember that the purpose of memorizing SAT words is to apply, so don't just memorize them.
