Web(a - b) 2 This can also be written as: = (a - b) (a - b) Multiply as we do multiplication of two binomials and we get: = a(a - b) - b(a - b) = a 2 - ab - ab + b 2 Add like terms and we … WebTo find the formula of (a - b) 2, we will just multiply (a - b) (a - b). (a - b) 2 = (a - b) (a - b) = a 2 - ab - ba + b 2 = a 2 - 2ab + b 2 Therefore, (a - b) 2 formula is: (a - b) 2 = a 2 - 2ab + b 2 Proof of A minus B Whole Square … Weba square plus b square formula a 2 + b 2 Formula. To calculate the sum of two or more squares in an expression, the a 2 + b 2 formula is used. The a 2 + b 2 formula can be easily derived using the (a+b) 2 or (a-b) 2 formula.
