Definition. In arithmetic, we often come across the sum of n natural numbers. There are various formulae and techniques for the calculation of the sum of squares. Let us write some of the forms with respect to two numbers, three numbers and n numbers. x 2 + y 2 → Sum of two numbers x and y. x 2 +y 2 +z 2 → Sum of three numbers x, y and z.
Formula: (x+y)² = x²+2xy+y² The square of the sum x and y is the square of the first term, plus twice the product of the first and last term, plus the square of the last term
The statement "the sum of the squares of x and y is equal to the square root of the difference of x and y" can be mathematically represented as : x2 +y2 =√x−y. (x+y)2 = √x−√y. √x+y =(x−y)2. x2 −y2 =√x+y. A. x2 +y2 = √x−y. B. √x+y =(x−y)2. C. x2 −y2 = √x+y. D. (x+y)2 = √x−√y. Solution. Verified by Toppr.
The square of the sum of x and y: (x+y)^2. Expanding it, we get... x^2 + 2xy + y^2 (4+3)^2 = 25+12+9 = 46. Therefore, the square of the sum of x and y is x^2 + 2xy + y^2, and in the case of x=4 and y=3, the square of the sum of x and y is 46.
Definition. The square of the sum of two expressions is equal to the square of the first, plus twice the product of the first and second, plus the square of the second: ( a + b) 2 = a2 + 2 ab + b2. Derivation of the formula of square of the sum. The proof of the formula is very simple. To prove the formula is sufficient to multiply the expression:
