1.	Fill in the blanks to make the statement true:(a – b) _________ = a2 – 2ab + b2
Answer» (a – b) (a – b) = (a – b)²= a² – 2ab + b² (a – b) (a – b) = a × (a – b) – b × (a – b) = a² – ab – ba + b² = a² – 2ab + b²

Fill in the blanks to make the statement true:(a – b) _________ = a2 – 2ab + b2

Answer»

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

(a – b) (a – b) = a × (a – b) – b × (a – b)

= a² – ab – ba + b²

= a² – 2ab + b²
