### Important Algebraic Formulas a2 b2 formula

(a+ b)² = ‘+b2+ 2ab

(a-b)² = d+b²- 2ab

a?- b² = (a+ b) (a– b)

a’+ b² = (a+ b)²- 2ab

a² + b² = (a-b)?+ Zab

0r

a² +b³ = (a+ b)(a² – ab + b²) =

(a + b)³ – 3ab (a + b)

a²-b³ = (a- b) (a²+ ab + b²) = (a-b)³ + 3ab(a- b)

2(a²+ b²y) = (a+ b)²+ (a- b)

(a+ b)²-(a- b)² – 4ab

at+ b+ = (a+ b) (a- b)[(a + b)²– 2ab]

(a- b)² = (a+b)²– 4ab

(a+ b)² = (a-b)² + 4ab

at+ b²= [(a+ b)²- 2ab]²- 2(aby²

(a+ b+c)² = +b²+²+ 2ab + 2bc+ 2ca

(a+ b-c)²= a’+b² + c² +2ab- 2bc- 2ca

(a-b-c)² = +b² + c²-2ab + 2bc-2ca

a’+b +c- 3abc = (a+ b+ c) (a’+b² +c’ ab- bc- ca)

a+ a?b +b= (a+ ab + b)(a²- ab + b²

at+a’+ 1= (a’ +a+ 1)(a’-a+1)

if a +b+c=0 then a+b² + c= 3abc

a-b- (at+b”) (a²+ b²) (a + b) (a– b)

(a + b)2 Formula

**You can express (a + b} in two ways.**

It is as follows

a + 6) a’ + 2ab +

(a+ 6) = (a– 6 + 4ab

(a-b)2 Formula

**You can express (a – b} in two ways**.

It is as follows

(a – 6)2 = a’ – 2ab + 62

(a + 6 = (a – 6) – 4ab

a2 + b2 Formula

**You can express a’ + b in two ways**.

It is as follows

a’+be = (a+6}² – 2ab

a’+be = (a+6) + 2ab

a? – b Formula

**You can express a’ + b² in two ways**.

It is as follows

a’- 6= a + 6) (a – b)

### How to use a2 b2 c2 formula

a² + b² + c² = (a +b + c)² – 2ab – 2bc – 2ca

a² + b2 + c² = (a +b + c)² – 2(ab + bc + ca)
