Question

math part 2 9th formula​

Answer 1

Answer:

9th Class Formulas For Algebraic Identities

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

(a – b)2 = a2 – 2ab + b2

(a + b) (a – b) = a2 -b2

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

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

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

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

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