Question

The factors of x2+y2 how is this solve

Answer 1

2, because it was common in both x2 and y2

Answer 2

${\bf{\blue{hOlA}}}$

Factors of x²+y² are=x²+y²+2xy

We can verify it by solving the L.HS.

x²+y² can be written as

=(x+y)×(x+y)

now,

=x(x+y)+y(x+y)

=x²+xy+yx+y²

=x²+2xy+y²

${\pink{\bf{Answer:-x^2+y^2+2xy}}}$
