expand sqrt((xa-xb)^2+(ya-yb)^2)

expand

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

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

Solution steps

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

Expand

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

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

(\frac{5 x + 3}{2 y + z})^{2}

\frac{1 + 64 m ^{3}}{1 + 4 m}

6 (2 e^{x^{2}} x^{2} + e^{x^{2}})

1 - [G_{1} (G_{3} + G_{2})] H_{1}

\frac{( 25 x + 16 )}{( x ( x + 1 ) ( x + 2 ) )}
