Mathematics
Now I show you eight ways to memorize math formulas in easy ways. Some students are afraid of studying mathematics formulas. But for me, mathematics is not only limited to learning from textbooks. It is about solving and easy ways to understanding with solving problems.
Mathematics formulas are the best way to make this subject for our goal lives. Therefore, learning math must be confidence and enhance our problems solving skills. Some of you are very tough and confusing to memorize all the math formulas in one go. So here is eight ways to memorize math formulas in an easy way.
1. Grow your interest in the concept in which you are studying: It is very important for you to concept something that you are interest in short words. It is always easier for understanding and learning.
2. Connect your concept with a visual memory: Visual memory is predominantly things that you can attach with each math formulas will help you to remember all steps of predominant.
3. Knowing the process behind math formulas: It is certain to know the entire reason or process that easier for us to remember as it makes more sense and helpful to memorize.
4. Always solve the problems: Practicing is the perfect ways for using repeatedly as repetition leads to memorization.
5. Write down math formulas: Write math repeated it again and again for our brain tend to remember as for long.
6. Stick your written formulas on the wall: Write down on plain paper or wall make sure your feeling tough slowly to your brain that help you to remember by seeing those.
7. Recall all math formulas before bedtime: Learning all that days before bed make sure your brain better chance of remembering.
8. Don't distract yourself while learning formulas: Give less attention to everything that distract you . You just focus on learning.

2. (α+в)²= (α-в)²+4αв
3. (α-в)²= α²-2αв+в²
4. (α-в)²= (α+в)²-4αв
5. α² + в²= (α+в)² - 2αв.
6. α² + в²= (α-в)² + 2αв.
7. α²-в² =(α + в)(α - в)
8. 2(α² + в²) = (α+ в)² + (α - в)²
9. 4αв = (α + в)² -(α-в)²
10. αв =1. (α + в + ¢)² = α² + в² + ¢² + 2(αв + в¢ + ¢α)
11. (α + в)³ = α³ + 3α²в + 3αв² + в³
12. (α + в)³ = α³ + в³ + 3αв(α + в)
13. (α-в)³=α³-3α²в+3αв²-в³
14. α³ + в³ = (α + в) (α² -αв + в²)
15. α³ + в³ = (α+ в)³ -3αв(α+ в)
16. α³ -в³ = (α -в) (α² + αв + в²)
17. α³ -в³ = (α-в)³ + 3αв(α-в)
