expand sqrt(x^2+(y-1)^2)

expand

x^{2} + (y - 1)^{2}

x^{2} + y^{2} - 2 y + 1

Solution steps

x^{2} + (y - 1)^{2}

Expand

x^{2} + (y - 1)^{2} : x^{2} + y^{2} - 2 y + 1

= x^{2} + y^{2} - 2 y + 1

(y + 6 i)^{2}

\frac{2 ( 2 2 - 1 )}{3}

(x + 8) (x - 8)

tan (3 x) (tan (x) - 1)

\frac{z - 1}{( z + 1 ) ( 3 z - 1 )}
