simplify (x^2-3x-18)/(x^2-15x+54)

simplify

\frac{x ^{2} - 3 x - 18}{x ^{2} - 15 x + 54}

\frac{x + 3}{x - 9}

Solution steps

\frac{x ^{2} - 3 x - 18}{x ^{2} - 15 x + 54}

Factor

x^{2} - 3 x - 18 : (x + 3) (x - 6)

= \frac{( x + 3 ) ( x - 6 )}{x ^{2} - 15 x + 54}

Factor

x^{2} - 15 x + 54 : (x - 6) (x - 9)

= \frac{( x + 3 ) ( x - 6 )}{( x - 6 ) ( x - 9 )}

Cancel the common factor:

x - 6

= \frac{x + 3}{x - 9}

\frac{7}{8} + \frac{7}{10}

- 2 x^{2} - 2

(6 - 35)^{2}

\frac{d}{d p} (e^{p ii})

\frac{4}{3} \times 9
