expand (arctan(y)-x)^2

expand

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

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

Solution steps

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

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

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

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

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

4 y (2 + 9) + 3

3 + \frac{2}{x}

4 - 21

4 x^{3} - 1 - x^{2} + 4 x

- 2 (y + 4) + 4 y
