Introduce me to do it, help me do it

During job interviews, most interviewers will ask candidates to introduce themselves, on the one hand, to understand the general situation of the candidates, and on the other hand, to examine the candidates' eloquence, adaptability, psychological tolerance, logical thinking and other abilities. Don't underestimate this self-introduction, it is not only a stepping stone to impress the interview examiner, but also an excellent opportunity to sell yourself, so be sure to take advantage of it. Candidates should pay attention to the following points:

1. After receiving the interview notice, it is best to make a draft of self-introduction at home, and then try to tell it a few times to feel it.

2. When introducing yourself, you should first politely make a very short opening statement and signal to all the interviewers (if there are more than one interviewer) that if the interviewer is paying attention to something else, you can wait a little longer and wait for him to turn around before starting.

3. Pay attention to the time, if the interview examiner sets the time, you must pay attention to the time, neither too long nor too short.

Fourth, the content of the introduction should not stay too much on things such as name, work experience, time, etc., because these are already on your resume form, you should talk more about the work experience and achievements related to the position you are applying for, in order to prove that you are indeed capable of the job position you are applying for.

Fifth, when making a self-introduction, the eyes should not look around, wander around, and appear careless, which will give people the feeling of doing things casually and inattentively. It's best to keep your eyes on the interviewer, but not for a long time. The second is to add as little hand support as possible, because this is not a lecture after all, and it is also important to maintain a proper posture.

6. Don't forget to say thank you after introducing yourself, which sometimes often affects the examiner's impression of you.

When the interviewer casually asks you, "Tell us about yourself?" "That's the first question in the interview.

At this point, you should stabilize all the tension that you had before that. Because of this question, the test taker has been well prepared and has enough confidence and courage to believe that he can do this question well.

2. Let the side length of the square be x

Then the remaining 48 square meters are a rectangle, which is x in length and x-248 in width = x* (x-2).

x=8, the original square area is 8*8=64

The unary quadratic equation 2x2+4x-1=0, the quadratic coefficient 2, the primary term coefficient 4, and the constant term coefficient -1, their sum is: (2+4-1)=5

12、-x=3x²-2x-5

3x²-x-5=0

x²-x/3+1/36=61/36

x-1/6)²=61/36

x=1/6+√61/6 x=1/6-√61/613、c=0

Let the two be x1 and x2

Multiply the two by x1*x2=c a

If there is a heel of 0

then c a=0

So c = 014, + root number 3 or - root number 3

15、x(x+2)=15

x²+2x-15=0

x-3）（x+5）=0

The solution yields x=3 or x=-5

So these two numbers are 3, 5 or -3 -5

16. Formula, factoring, formula.

Child: 20 points, I don't think anyone will do it, just now I did 4 questions, 50 points, all counted for about 10 minutes.

According to the inverse theorem of the Pythagorean theorem, the annihilation of this triangle BCD is a right-angled swift triangle, cd ab, and the triangle ADC is also a straight triangle, let AD 2+cd 2=AC 2, AC=AB, let AB=X, X-12) 2+16 2=X 2, x 2-24x+144+256=X 2,24x=400, X=50 3, the circumference of the triangle ABC=AB+AC+BC=50*2 3+20=160 3
