## Mathematical Formula

Competitive exams are fill with maths where you need mathematical formula. So, *Mathematical Formulas* are very important and necessary for doing maths.

Here in this page we put together all basic mathematical formula. You need these formulas in your exams. So, you need to memorize these math formula very carefully before your exam. 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 − b)
^{2}= a^{2}− 2ab + b^{2} - a
^{2}+ b^{2}= (a + b)^{2}− 2ab - a
^{2}+ b^{2}= (a − b)^{2}+ 2ab - (a + b)
^{3}= a^{3}+ b^{3}+ 3ab(a + b) - (a − b)
^{3}= a^{3}− b^{3}− 3ab(a − b) - a
^{3}+ b^{3}= (a + b)^{3}− 3ab(a + b) - a
^{3}− b^{3}= (a − b)^{3}+ 3ab(a − b) - a
^{2}− b^{2}= (a + b)(a − b) - a
^{3}− b^{3}= (a − b)(a^{2}+ ab + b^{2}) - a
^{3}+ b^{3}= (a + b)(a^{2}− ab + b^{2}) - a
^{4}– b^{4}= (a^{2}– b^{2})(a^{2}+ b^{2}) = (a + b)(a + b)(a^{2}+ b^{2}) - a
^{4}+ b^{4}= (a^{2}+ b^{2})^{2}– 2a^{2}b^{2}= (a^{2}+ √2ab + b^{2})(a^{2}– √2ab + 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}− b^{n}= (a − b)(a^{n−1}+ a^{n−2}b + a^{n−3}b^{2}+ ··· + b^{n−1}n−1) - (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

Geometry ka trick and salb bhejdijiye

Can you tell me the site for English Language preparation notes

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….

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 😇

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 you👍👍👍👍👍👍👍👍👍👍👍👍👍
