Answer 2

Question :-

(x+8)(x-2)

Identity to use :-

(x+a)(x+b) = x² + x(a+b) + ab

• a = 8
• b = (-2)

Applying the identity,

x² + x[8+(-2)] + (8)(-2)

x² + x(6) - 16

x² + 6x - 16

Some more identities :-

• (a + b)² = a² + 2ab + b²  

• (a – b)² = a² – 2ab + b²

• a²-b² = (a+b)(a-b)

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