Question

all formula of algebra plz write here..​

Answer 1

Answer:

Important Formulas in Algebra

a2 – b2 = (a – b)(a + b)

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

a2 + b2 = (a + b)2 – 2ab.

(a – b)2 = a2 – 2ab + b2

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

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

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

Answer 2

Answer:

Important Formulas in Algebra

a2 – b2 = (a – b)(a + b)

(a + b)2 = a2 + 2ab + b2

a2 + b2 = (a + b)2 – 2ab.

(a – b)2 = a2 – 2ab + b2

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

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

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