expand 1/(sqrt(4+9x^2))

expand

\frac{1}{4 + 9 x ^{2}}

\frac{4 + 9 x ^{2}}{4 + 9 x ^{2}}

Solution steps

\frac{1}{4 + 9 x ^{2}}

Multiply by the conjugate

\frac{4 + 9 x ^{2}}{4 + 9 x ^{2}}

= \frac{1 \cdot 4 + 9 x ^{2}}{4 + 9 x ^{2} 4 + 9 x ^{2}}

1 \cdot 4 + 9 x^{2} = 4 + 9 x^{2}

4 + 9 x^{2} 4 + 9 x^{2} = 4 + 9 x^{2}

= \frac{4 + 9 x ^{2}}{4 + 9 x ^{2}}

\frac{( 4 s + 5 )}{( ( s + 3 ) ( s - 4 ) ^{2} )}

(z^{2} + π^{2})^{2}

\frac{e ^{x} ( x - 3 )}{x ^{4}}

(4 E (x, y) x - 5 E (x, y) y = 14.17) x - 2

\frac{2 x + 2 sin ( 2 x ) ( x ^{2} + 1 )}{cos ( 2 x )}
