simplify (5n^2-245)/(7n^2+112n+441)

simplify

\frac{5 n ^{2} - 245}{7 n ^{2} + 112 n + 441}

\frac{5 ( n - 7 )}{7 ( n + 9 )}

Solution steps

\frac{5 n ^{2} - 245}{7 n ^{2} + 112 n + 441}

Factor

5 n^{2} - 245 : 5 (n + 7) (n - 7)

= \frac{5 ( n + 7 ) ( n - 7 )}{7 n ^{2} + 112 n + 441}

Factor

7 n^{2} + 112 n + 441 : 7 (n + 7) (n + 9)

= \frac{5 ( n + 7 ) ( n - 7 )}{7 ( n + 7 ) ( n + 9 )}

Cancel the common factor:

n + 7

= \frac{5 ( n - 7 )}{7 ( n + 9 )}

\frac{3}{4} - \frac{7}{8}

4 x^{2} + 20 = 0
