expand 2/(sqrt(9-2x))

expand

\frac{2}{9 - 2 x}

\frac{2 9 - 2 x}{9 - 2 x}

Solution steps

\frac{2}{9 - 2 x}

Multiply by the conjugate

\frac{9 - 2 x}{9 - 2 x}

= \frac{2 9 - 2 x}{9 - 2 x 9 - 2 x}

9 - 2 x 9 - 2 x = 9 - 2 x

= \frac{2 9 - 2 x}{9 - 2 x}

\frac{1}{( ( y - 1 ) ( y ^{2} + 1 ) )}

\frac{1}{5 ( 15 a + b )}

2 (x - 3) - (\frac{19}{x - 3}) + 12 ln ∣ x - 3 ∣ + C

3 \cdot π (805 - 64)

2 (- \frac{ln ( x )}{4 x ^{4}} - \frac{1}{16 x ^{4}}) + C
