expand 2a-sqrt((x-c)^2+y^2)

expand

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

2 a - x^{2} - 2 c x + c^{2} + y^{2}

Solution steps

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

Expand

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

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

(x^{7})^{2}

\frac{( x + h ) ^{2} - 3 ( x + h ) + 4}{h}

(x + 3) + \frac{x + 7}{2 - x}

- e^{0}

2 π (c^{3} - \frac{c ^{7}}{7})
