expand sqrt((P-J)^2+(Q-K)^2)

expand

(P - J)^{2} + (Q - K)^{2}

P^{2} - 2 P J + J^{2} + Q^{2} - 2 Q K + K^{2}

Solution steps

(P - J)^{2} + (Q - K)^{2}

Expand

(P - J)^{2} + (Q - K)^{2} : P^{2} - 2 P J + J^{2} + Q^{2} - 2 Q K + K^{2}

= P^{2} - 2 P J + J^{2} + Q^{2} - 2 Q K + K^{2}

(a + 55)^{2}

3 (1 + \frac{2 i}{n})^{2}

\frac{15 x ^{2} - 10 x + 16}{( 3 x - 1 ) ^{2}}

\frac{1}{y ( y - 1 )}

x \times (x^{2} + 1)
