Answer 1

Answer:

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

(a − b)2 = a2 − 2ab + b2

a2 + b2 = (a + b)2 − 2ab

a2 + b2 = (a − b)2 + 2ab

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

(a − b)3 = a3 − b3 − 3ab(a − b)

a3 + b3 = (a + b)3 − 3ab(a + b)

a3 − b3 = (a − b)3 + 3ab(a − b)

a2 − b2 = (a + b)(a − b)

a3 − b3 = (a − b)(a2 + ab + b2)

a3 + b3= (a + b)(a2 − ab + b2)

a4 – b4 = (a2 – b2)(a2 + b2) = (a + b)(a + b)(a2 + b2)

a4 + b4 = (a2 + b2)2 – 2a2b2 = (a2 + √2ab + b2)(a2 – √2ab + b2)

a5 + b5 = (a + b)(a4 – a3b + a2b2 – ab3 + b4 )

a5 – b5 = (a – b)(a4 + a3b + a2b2 + ab3 + b4)
