Question

all the formulas of algebra​

Answer 1

Answer:

Step-by-step explanation:

The formulas of algebra are as shown below:

$(a+b)^{2}=a^{2}  +b^{2} +2ab\\(a-b)^{2}=a^{2}+ b^{2}-2ab\\a^{2}- b^{2}=(a+b)(a-b)\\  (a^{2} +b^{2} )=(a+b)^{2}-2ab\\ (a^{3} +b^{3} )=(a+b)(a^{2}-ab+b^{2} )\\\\(a^{3} -b^{3} )=(a-b)(a^{2}+ab+b^{2} )$

$(a+b+c)^{2}=a^{2}+ b^{2}+ c^{2}+2ab+2bc+2ca\\(a-b-c)^{2}=a^{2}+ b^{2}+ c^{2}+2ab-2bc-2ca$
