expand (x(x-1))/((x+7)(x-6))

expand

\frac{x ( x - 1 )}{( x + 7 ) ( x - 6 )}

\frac{x ^{2} - x}{x ^{2} + x - 42}

Solution steps

\frac{x ( x - 1 )}{( x + 7 ) ( x - 6 )}

Expand

(x + 7) (x - 6) : x^{2} + x - 42

= \frac{x ( x - 1 )}{x ^{2} + x - 42}

Expand

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

= \frac{x ^{2} - x}{x ^{2} + x - 42}

\frac{x ^{2} + 2 x + k}{2 ( x + 2 )}

(2, - 3) y (- 5, 4)

\frac{2 x + 3}{( x - k ) ( x + 4 )}

50 (1 - 0.4 e^{4 x})

\frac{( 2 x + 1 ) ^{3}}{6}
