simplify x/(sqrt(4-x^2))

simplify

\frac{x}{4 - x ^{2}}

\frac{x 4 - x ^{2}}{4 - x ^{2}}

Solution steps

\frac{x}{4 - x ^{2}}

Multiply by the conjugate

\frac{4 - x ^{2}}{4 - x ^{2}}

= \frac{x 4 - x ^{2}}{4 - x ^{2} 4 - x ^{2}}

4 - x^{2} 4 - x^{2} = 4 - x^{2}

= \frac{x 4 - x ^{2}}{4 - x ^{2}}

- (x - 4)

(2 + 3 x + x^{2}) \cdot (2 + x)

4 b + 6 - 4

1 + 3.322 \cdot lo g_{10} (20)
