- (x + a)(x – b) = x2 + (a – b)x – ab
- (a + b)3 = a3 + b3 + 3ab(a + b)
- (a – b)3 = a3 – b3 – 3ab(a – b)
- (x – a)(x + b) = x2 + (b – a)x – ab
- (x – a)(x – b) = x2 – (a + b)x + ab
- (x + y + z)2 = x2 + y2 + z2 + 2xy + 2yz + 2xz
- (x + y – z)2 = x2 + y2 + z2 + 2xy – 2yz – 2xz
- (x – y + z)2 = x2 + y2 + z2 – 2xy – 2yz + 2xz
- (x – y – z)2 = x2 + y2 + z2 – 2xy + 2yz – 2xz
- x3 + y3 + z3 – 3xyz = (x + y + z)(x2 + y2 + z2 – xy – yz -xz)
- x2 + y2 =½ [(x + y)2 + (x – y)2]
- (x + a) (x + b) (x + c) = x3 + (a + b +c)x2 + (ab + bc + ca)x + abc

**Tips to Memorise Class 10 Maths Formulas**

To effectively understand and recall all of the formulas required for class 10 mathematics, it is important to follow some helpful tips. These tips can make it easier to remember formulas in the long run and can improve your overall comprehension of the subject.

**Tip 1: Create Mnemonics**

Mnemonics are useful memory aids that use a combination of words, letters, numbers, and images to help you recall formulas quickly. By creating your own mnemonics, you can develop a personalized system for remembering mathematical formulas. Explore the various methods below to discover how you can create effective mnemonics for your own use.

Here are the four ways to remember mnemonics better:

**[1] Acronyms**

One effective way to remember formulas is to create an acronym by taking the first letter of each word in the formula. This can help to easily recall the formula when needed. For instance, the value of Pi (π) to 7 decimal places can be remembered using the acronym “May I have a large container of coffee?”, with each word representing a digit – 3.1415926.

**[2] Rhymes**

**Rhymes to find the Area of a circle**

“To find the area of a round space,

Pi times radius squared is the case.”

**Another one for the Pythagorean Theorem**

“To find the side that is unknown,

Square the two that are clearly shown.

Add them up, and then you’ll see,

The square root is the missing degree.”

By using the mnemonics it becomes easier to recall formulas, which directly helps us to solve problems and make our calculations more efficient.

**Tip 2: Break It Down**

Breaking down a formula into its individual components can be a helpful way to understand how they all relate to one another. This approach makes it easier to comprehend and remember the formula. By identifying the variables and practicing their use, you can become more proficient in applying the formula and arriving at the correct result.

**Tip 3: Repetition**

Repetition is a highly effective method for learning mathematical formulas more quickly. Repeating a formula multiple times helps to reinforce it in your memory and makes it easier to recall. There are several ways to incorporate repetition into your studying, such as taking quizzes, using flashcards, daily practice, repeating formulas in various formats, and regular repetition. Through consistent repetition, a formula becomes more familiar and ingrained in your memory, making it easier to recall in the long run.

**Conclusion**

All the formulas for class 10 math have been listed above, so students don’t need to search for them elsewhere. By practicing these formulas, you can improve your preparation and become more proficient in solving mathematical problems with speed and accuracy. Furthermore, a solid understanding of these formulas can help you tackle more advanced math questions with confidence. Strengthening your preparation through regular practice is crucial for achieving success in mathematics.
