化简 p/((2sqrt(p)-1))

解答

化简

\frac{p}{( 2 p - 1 )}

\frac{p ( 2 p + 1 )}{4 p - 1}

求解步骤

\frac{p}{2 p - 1}

乘以共轭根式

\frac{2 p + 1}{2 p + 1}

= \frac{p ( 2 p + 1 )}{( 2 p - 1 ) ( 2 p + 1 )}

(2 p - 1) (2 p + 1) = 4 p - 1

= \frac{p ( 2 p + 1 )}{4 p - 1}

e x p an d (2 a + 3 b + 5) (2 a - 3 b + 5)

f a c t or x^{4} + y^{4} - 2 x^{2} y^{2}

s im pl i f y \frac{4 x ^{2} - 4 y ^{2}}{x ^{2} - 3 x y - 4 y ^{2}}

s im pl i f y (\frac{2}{3 x + 3 y})^{3}

e x p an d (x + 2 y)^{3} - 1
