How can the homework be completed super fast?! Urgent! Urgent! Urgent! Urgent! Urgent!

Use your own brain. Calm down. Or set a goal for yourself.

For example, what homework can be done after writing. Try to discipline yourself. The important thing is to look at yourself, but also to concentrate, copy the homework faster, it's okay to be sloppy, and write a little more about the information, taking up a point.

Adopt mine, thanks).

Well, of course, you have to be attentive, and it's better to write in a quiet evening, under bright lights, so it's easier to concentrate. As long as you write carefully, you will unconsciously get used to this atmosphere of writing homework, and you will be more attentive to writing like that. If you are writing an essay such as a search for information, you can write a larger word.

The easiest thing is to copy homework or let others write it, but it is not recommended.

If the summer vacation winter vacation homework answers are right or wrong, it doesn't matter, be quick! I scribble every time, the teacher doesn't check right or wrong, so many homework, go to his tm shit homework. If you want to do your homework, write it slowly!

You can copy it! RMB speed solves the problem, ·! Or use your brain, think about what the teacher said in class, flip through your notes, and you'll be fine in no time!Or hit ** and ask the teacher!

Just concentrate! It's definitely okay to concentrate and meditate!

Concentration is the most important thing

You need to know what you're going to write about.

Then look for information.

565+6 Sada asks, ah, ah, great doll.

1) The actual salary is yuan.

2) The tax payable is RMB.

3) The monthly income is RMB.

Assuming that -2 is not multiplied by 3, then the equation becomes: 2x-1=x+a-2; At this time, x=2, and substituting the formula gives 2*2-1=2+a-2; a=3。Substituting a=3, and removing the denominator to the original formula yields:

2x-1=x+3-2*3 ;Shift the term to get 2x-x=3-6+1; x=-2

-2 on the right side of the equation is not multiplied by 3, and is brought in according to the wrong algorithm. 2x-1=x+a-2, bring in x=2, find a=3. Then bring a=3 into the original equation and solve x

I'm sorry, I just saw the title... Actually, I have a simple and clear method with you!!

I can't finish it, and no one helps me...

With the root finding formula, there are two real roots when the formula is zero or when. I can't remember exactly.
