simplify (x^2-x-90)/(x^2-17x+70)

simplify

\frac{x ^{2} - x - 90}{x ^{2} - 17 x + 70}

\frac{x + 9}{x - 7}

Solution steps

\frac{x ^{2} - x - 90}{x ^{2} - 17 x + 70}

Factor

x^{2} - x - 90 : (x + 9) (x - 10)

= \frac{( x + 9 ) ( x - 10 )}{x ^{2} - 17 x + 70}

Factor

x^{2} - 17 x + 70 : (x - 7) (x - 10)

= \frac{( x + 9 ) ( x - 10 )}{( x - 7 ) ( x - 10 )}

Cancel the common factor:

x - 10

= \frac{x + 9}{x - 7}
