## Mathematical Formula

Competitive exams

*Mathematical Formulas*are very important and necessary for doing maths.

So, here in this page we put together all basic mathematical formula. And, you need these formulas in your exams. Basically, these are the basic formulas which you all did in our school days. During Class 6, Class 7, Class 8, Class 9, Class 10 you did these formulas. Firstly, you need to memorize these math formula very carefully before your exam. So, that you can apply it properly in your exams. And, trust me it is very easy to remember. So, here we provide few basic mathematical formula which will help you to do maths in your competitive exams.

**All Algebra Formula:**

- (a + b)
^{2}= a^{2}+ 2ab + b^{2} - (a β b)
^{2}= a^{2}β 2ab + b^{2} - a
^{2}+ b^{2}= (a + b)^{2}β 2ab - a
^{2}+ b^{2}= (a β b)^{2}+ 2ab - a
^{2}+ b^{2}= Β½{(a + b)^{2}+ (a – b)^{2}} - a
^{2}β b^{2}= (a + b)(a β b) - (a + b)
^{3}= a^{3}+ b^{3}+ 3ab(a + b) - (a β b)
^{3}= a^{3}β b^{3}β 3ab(a β b) - a
^{3}+ b^{3}= (a + b)^{3}β 3ab(a + b) - a
^{3}β b^{3}= (a β b)^{3}+ 3ab(a β b) - a
^{3}β b^{3}= (a β b)(a^{2}+ ab + b^{2}) - a
^{3}+ b^{3}= (a + b)(a^{2}β ab + b^{2}) - a
^{4}– b^{4}= (a^{2}– b^{2})(a^{2}+ b^{2})Β = (a + b)(a – b)(a^{2}+ b^{2}) - a
^{4}Β + b^{4}= (a^{2}+ b^{2})^{2}– 2a^{2}b^{2}= (a^{2}+ β2ab + b^{2})(a^{2}– β2ab + b^{2}) - a
^{5}+ b^{5}= (a + b)(a^{4}– a^{3}b + a^{2}b^{2}– ab^{3}+ b^{4}) - a
^{5}– b^{5}= (a – b)(a^{4}+ a^{3}b + a^{2}b^{2}+ ab^{3}+ b^{4}) - a
^{n}β b^{n}= (a β b)(a^{nβ1}+ a^{nβ2}b + a^{nβ3}b^{2}+ Β·Β·Β· + b^{nβ1}nβ1) - (a + b + c)
^{2}= a^{2}+ b^{2}+ c^{2}+ 2(ab + bc + ca) - a
^{3}+ b^{3}+ c^{3}– 3abc = (a + b + c)(a^{2}+ b^{2}+ c^{2}– ab – bc – ca) - If a + b + c = 0, then the above identity reduces to a
^{3}+ b^{3}+ c^{3}= 3abc

Yes

Sir bht axcha h ye pd kr bht mja aya

But khub

i really enjoyed this site..all the shortcuts and formulas at one site..extraordinary… it would be nice if mensuration formulas included…

Thanx acha lga

great just great…. tnxxx Editor & admin….

i really enjoyed this site..all the shortcuts and formulas at one site..extraordinaryβ¦ it would be nice if mensuration formulas includedβ¦

This site is very useful when one forgot a fourmula.

This site is very useful

Iwhen I forget formulas then I see this

Nice just

nicee

nice π

its very nice and helpful

Its very usefull to every on thaks browser to update such kind of things ….

Thanks sir

Good for everyone

Thanks

Good for everyone

Better. For students

its really good

ser kya muje 12 ke sare importent formula mil sakte he please ser

12 me Sara importent farmula mil sakta hai please ser

Yes it ts best for all student

Nice shortcut formula… Thanks.

Nice and Amazing questions but padne me achha lga enhe padne se hamare mind ka vikas hota or jab i enko soul krta hu to muje very achha lagta h I’m happy read that question thank youπππππππππππππ

Thanks

all this type of formula are useful for the student and i encourage to develop this type formula to be done more and to upload i really thanks to person who uploaded this formula

Nice… But do you have any link I can use to download a mathematics textbook with all those topics in them… Thanks

Nice sir

nice

thank u so much i leart so many things
