See tutors like this Shravan, It looks like you are asking to factor the polynomial WebThe a^2 + b^2 formula is used to calculate the sum of two or more squares in an expression. Thus, a sum of squares formula or a^2 + b^2 formula can be expressed as: a 2 + b 2 = (a +b) 2 - 2ab. Also, a 2 + b 2 = (a - b) 2 + 2ab. where, a, b = arbitrary numbers. Let a and b be the two numbers, the squares of a and b are a 2 and b 2. comparing vhi plans
