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

expand

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

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

Solution steps

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

Expand

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

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

Expand

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

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

(2 + x + x^{4}) (5 x - \frac{1}{2 x ^{3}})^{8}

A (- 4, - 5) B (- 2, 3) C (1, - 2)

\frac{( 3 x - 1 ) ^{2}}{9}

\frac{( 3 x - 1 )}{x ( x - 4 )}
