expand ((x+2)(x-1))/((x-5)(x+4))

expand

\frac{( x + 2 ) ( x - 1 )}{( x - 5 ) ( x + 4 )}

\frac{x ^{2} + x - 2}{x ^{2} - x - 20}

Solution steps

\frac{( x + 2 ) ( x - 1 )}{( x - 5 ) ( x + 4 )}

Expand

(x - 5) (x + 4) : x^{2} - x - 20

= \frac{( x + 2 ) ( x - 1 )}{x ^{2} - x - 20}

Expand

(x + 2) (x - 1) : x^{2} + x - 2

= \frac{x ^{2} + x - 2}{x ^{2} - x - 20}

\frac{q ^{6}}{q ^{4}}

4 - 2 ln (8)

\frac{3 s + 4}{( s + 1 ) ( s + 2 )}

240 \cdot \frac{9 + 8 i}{9.5 + 8.2 i}

((1 + t) \cdot ln ∣ x ∣) - ((1 + 3 t) \cdot ln ∣ y ∣)
