Question

what is the formula of algerbic​

Answer 1

The formulas for algebra are :-

(a – b)² = a² – 2ab + b²

a² – b²= (a + b)(a – b)

(x + a)(x + b) = x² + (a + b) x + ab

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

(a + b)³ = a³ + b³ + 3ab (a + b)

(a – b)³ = a³ – b³ – 3ab (a – b)

a³ + b³ + c³ – 3abc = (a + b + c)(a² + b² + c² – ab – bc – ca)
