simplify (x-y)^2-x^2+y^2

simplify

(x - y)^{2} - x^{2} + y^{2}

- 2 x y + 2 y^{2}

Solution steps

(x - y)^{2} - x^{2} + y^{2}

Expand

(x - y)^{2} : x^{2} - 2 x y + y^{2}

= x^{2} - 2 x y + y^{2} - x^{2} + y^{2}

Group like terms

= x^{2} - x^{2} - 2 x y + y^{2} + y^{2}

Add similar elements:

x^{2} - x^{2} = 0

= - 2 x y + y^{2} + y^{2}

Add similar elements:

y^{2} + y^{2} = 2 y^{2}

= - 2 x y + 2 y^{2}

\frac{( x + 15 )}{( x ^{2} - 9 )} + \frac{2}{( x + 3 )}

(a^{6})^{2}

\frac{4 + 2 \cdot ( 1 + 8 x ^{9} ) - 7 + 12}{4}

\frac{( cos ^{2} ( t ) - 1 )}{2}
