simplify 2/((s-2)^2+4)-1/(s-2)

simplify

\frac{2}{( s - 2 ) ^{2} + 4} - \frac{1}{s - 2}

\frac{2}{s ^{2} - 4 s + 8} - \frac{1}{s - 2}

Solution steps

\frac{2}{( s - 2 ) ^{2} + 4} - \frac{1}{s - 2}

Expand

(s - 2)^{2} : s^{2} - 4 s + 4

= \frac{2}{s ^{2} - 4 s + 4 + 4} - \frac{1}{s - 2}

Add the numbers:

4 + 4 = 8

= \frac{2}{s ^{2} - 4 s + 8} - \frac{1}{s - 2}

\frac{5 x ^{4} y ^{5}}{- 6 x ^{4} y}

\frac{1}{4} \cdot (- 4)

\frac{x}{3} + \frac{x}{2}

(3^{3})^{- 2}

\frac{1}{2} 3
