simplify (x^2-8x+7)/(x^2+7x-8)

simplify

\frac{x ^{2} - 8 x + 7}{x ^{2} + 7 x - 8}

\frac{x - 7}{x + 8}

Solution steps

\frac{x ^{2} - 8 x + 7}{x ^{2} + 7 x - 8}

Factor

x^{2} - 8 x + 7 : (x - 1) (x - 7)

= \frac{( x - 1 ) ( x - 7 )}{x ^{2} + 7 x - 8}

Factor

x^{2} + 7 x - 8 : (x - 1) (x + 8)

= \frac{( x - 1 ) ( x - 7 )}{( x - 1 ) ( x + 8 )}

Cancel the common factor:

x - 1

= \frac{x - 7}{x + 8}
