simplify 3(sqrt(1-x^2)-(x^2)/((1-x^2)^{1/2)})

simplify

3 (1 - x^{2} - \frac{x ^{2}}{( 1 - x ^{2} ) ^{\frac{1}{2}}})

\frac{3 ( 1 - 2 x ^{2} )}{( 1 - x ^{2} ) ^{\frac{1}{2}}}

Solution steps

3 (1 - x^{2} - \frac{x ^{2}}{( 1 - x ^{2} ) ^{\frac{1}{2}}})

Join

1 - x^{2} - \frac{x ^{2}}{( 1 - x ^{2} ) ^{\frac{1}{2}}} : \frac{1 - 2 x ^{2}}{( 1 - x ^{2} ) ^{\frac{1}{2}}}

= 3 \cdot \frac{1 - 2 x ^{2}}{( 1 - x ^{2} ) ^{\frac{1}{2}}}

Apply the fraction rule:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{3 ( 1 - 2 x ^{2} )}{( 1 - x ^{2} ) ^{\frac{1}{2}}}

\frac{1}{2} (lo g_{10} (x) y - lo g_{10} (7))

(sin (m) - tan (m)) (cos (m) - cot (m))

\frac{x ^{2} + x + 4}{( x + 2 ) ( x ^{2} - 9 x + 2 )}

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

\frac{( x - 2 ) ( x + 2 )}{x - 4}
