Evaluate using the identify (a – b)2 = a2 – 2ab + b2.592

1.	Evaluate using the identify (a – b)2 = a2 – 2ab + b2.592
Answer» 59² = (60 – 1)² (a – b)² = a² – 2ab + b² Here a = 60, b = 1 (60 – 1)² = 60² – (2)(60)(1) +12 = 3600 – 120 + 1 59² =3481

Answer»

59² = (60 – 1)² (a – b)² = a² – 2ab + b²

Here a = 60, b = 1

(60 – 1)² = 60² – (2)(60)(1) +12

= 3600 – 120 + 1 59² =3481
