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

expand

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

\frac{x ^{2} + 2 x - 8}{x ^{2} - 5 x + 4}

Solution steps

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

Expand

(x - 1) (x - 4) : x^{2} - 5 x + 4

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

Expand

(x - 2) (x + 4) : x^{2} + 2 x - 8

= \frac{x ^{2} + 2 x - 8}{x ^{2} - 5 x + 4}

(2 p x y) d x + (x^{2} + p y^{2}) d y

b (a (a + b))

- \frac{x ( x - 1 ) ( x - 2 ) ( x - 4 )}{8}

x^{2} x^{3}

(n^{7})^{2} - n^{2}
