I need the help of good people, and good people must help me

First of all, you have to make sure that you really like her, after this is established, you have to be firm in your position, you can't give up, sometimes girls will also like those stupid and stupid boys (not to say you, hehe), because to give girls a feeling that boys are more honest, it will also give her a sense of security And like a person's expression to her does not have to rely on the mouth, as long as you have sincerity, any difficulties can be solved, and the girl you like I believe will also be in the eyes, come on! Step up your game!

There's nothing to be afraid of, if even the girl you like has such an attitude, then there will be no results in your career in the future, I hope you can be refreshing, brave, I believe she will like you, as long as you are sincere, but some girls will test you, so you can't give up.

I remember a classic line from a TV show

Love is to be spoken out loud.

But I can also tell you helplessly

A lot of times, feelings are just a one-person thing

What I want to say is, as long as you do your best to fight for this relationship, you don't have any regrets, don't love someone, but keep it in your heart

It's just too painful

Don't hesitate, but what the result is

It's up to you to fight for your feelings

The only thing you have to do is give yourself a sense of confidence!

Finally, I wish you the pursuit of her you like!

Change yourself from scratch and learn more from your classmates and friends about your opinions!

Friend, I'm the same as you. I chose to give up because I really had a lot of shortcomings. Even if you're together, you don't know what to do. So don't look for girls who are too difficult.

Be sincere, no matter what the outcome may be.

You help her when it matters most.

Look at her attitude towards you.

1: Let a+b=m a-b=n so the original formula = (n+4ab n)(m-4ab m)=mn+4abm n-4abn m-16a b mn

mn+4abm²/mn-4abn²/mn-16a²b²/mn

mn+4ab(m²-n²-4ab)/mn=mn+4ab(a²+2ab+b²-a²+2ab-b²-4ab)/mn

mn+4ab·0/mn=mn=(a+b)(a-b)=a²-b²

Because a=3 2, b=-1 2, then a-b =2

2: Because a*b=1 a+1 b, (x-2)*(x-4)=1 (x-2)+1 (x-4)=1 (2-x).

Shift: 2 (x-2)+1 (x-4)=0 Multiply both sides by (x-2) (x-4) at the same time

Get: 2x-8+x-2=0 3x=10 x=10 3

1. It is done with complete squares, and then substituted.

2. Change the two factors before the equal sign to the reciprocal, and then go to the denominator.
