simplify (x^2+2x-63)/(x^2-49)

simplify

\frac{x ^{2} + 2 x - 63}{x ^{2} - 49}

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

Solution steps

\frac{x ^{2} + 2 x - 63}{x ^{2} - 49}

Factor

x^{2} + 2 x - 63 : (x - 7) (x + 9)

= \frac{( x - 7 ) ( x + 9 )}{x ^{2} - 49}

Factor

x^{2} - 49 : (x + 7) (x - 7)

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

Cancel the common factor:

x - 7

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

\frac{8}{6} + \frac{7}{42}

3 x (2 x - 5)

- 4 r^{- 8} s^{0}

\frac{56}{7}
