what is the formula of x 2 y 2

What is the Formula of X ²+Y ²?

A polynomial is composed of solely added, subtracted, and multiplied terms. Ax2 + bx + c is indeed the form of a quadratic function in x of real coefficients, in which a, b, and c are real integers with a 0. The degree in polynomials refers towards the variable’s greatest exponent inside the polynomial. Algebraic identities are algebraic equations that are accurate for any and all values of the independent variable in them. Polynomial factorization is also done using them.

As you know, (a+b)2 can be represented as a2+2ab+b2, so if we put – (a+b)2 and also the 2ab solely on a single side, the remainder of the solution will be provided for this half. So, if we ask the same question using the same approach,

(x+y)2=x2+2xy+y2

x2+y2=(x+y)2−2xy
