Question

In maths there is a

12 formulas

like

a³-b³=(a-b) ( a²+b²+ab)
( a+b )²= a²+2ab+b²
( a-b) ²= a²-2ab+b²


like this only 12 formulas

is there

plz can any body send me

full 12 formulas also​

Answer 1

Step-by-step explanation:

(a + b)2 = a2 + 2ab + b2

(a + b)2 = (a - b)2 + 4ab

(a - b)2 = a2 - 2ab + b2

(a - b)2 = (a + b)2 - 4ab

a2 - b2 = (a + b)(a - b)

(x + a)(x + b) = x2 + (a + b)x + ab

(a + b)3 = a3 + 3a2b + 3ab2 + b3

(a + b)3 = a3 + 3ab(a + b) + b3

(a - b)3 = a3 - 3a2b + 3ab2 - b3

(a - b)3 = a3 - 3ab(a - b) - b3

a3 + b3 = (a + b)(a2 - ab + b2)

a3 - b3 = (a - b)(a2 + ab + b2)

a3 + b3 = (a + b)3 - 3ab(a + b)

a3 - b3 = (a - b)3 + 3ab(a - b)

Answer 2

Answer:

a

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