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

expand

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

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

Solution steps

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

Expand

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

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

\frac{x ^{2}}{( x - 2 ) ( x + 2 )}

\frac{3}{( s ^{2} + 9 w ^{2} ) ^{2}}

(6, - 3) y Q (- 2, - 3)

(sin (x) + cos (e) x)^{2}

2 (x - 3 = \frac{1}{2} (4 x - 12))
