## Mathematical Formula

Mathematical Formulas are very important and necessary for doing maths. 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
