expand sqrt(x^2+(y-3)^2)

expand

x^{2} + (y - 3)^{2}

x^{2} + y^{2} - 6 y + 9

Solution steps

x^{2} + (y - 3)^{2}

Expand

x^{2} + (y - 3)^{2} : x^{2} + y^{2} - 6 y + 9

= x^{2} + y^{2} - 6 y + 9

\frac{x - 2}{( x + 9 ) ( x - 5 )}

- \frac{5}{4} x^{2} + 120 x - \frac{940}{3}

\frac{( x + 1 ) \cdot 2}{x ^{2} + 1}

5^{2} 3^{2}

\frac{a - 3}{3 ( a - 4 )}
