expand (x^2-7)/((x+4)(x-7))

expand

\frac{x ^{2} - 7}{( x + 4 ) ( x - 7 )}

\frac{x ^{2} - 7}{x ^{2} - 3 x - 28}

Solution steps

\frac{x ^{2} - 7}{( x + 4 ) ( x - 7 )}

Expand

(x + 4) (x - 7) : x^{2} - 3 x - 28

= \frac{x ^{2} - 7}{x ^{2} - 3 x - 28}

(x \circ x + 8) (x)

(x^{2} sin (x) + 4 y) d y

(4, - 1, 0) (8 x - 4 y + z + 9 = 0)

\frac{3 Q ( 80000 - Q )}{2000}

x^{3} (x^{3} + 2 x + 3)^{2} d x
