## Mathematical Formula for Competitive Exams

Competitive exams are fill with maths where you need mathematical formula. So, *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
