simplify (a^2-a-20)/(a^2-7a+10)

simplify

\frac{a ^{2} - a - 20}{a ^{2} - 7 a + 10}

\frac{a + 4}{a - 2}

Solution steps

\frac{a ^{2} - a - 20}{a ^{2} - 7 a + 10}

Factor

a^{2} - a - 20 : (a + 4) (a - 5)

= \frac{( a + 4 ) ( a - 5 )}{a ^{2} - 7 a + 10}

Factor

a^{2} - 7 a + 10 : (a - 2) (a - 5)

= \frac{( a + 4 ) ( a - 5 )}{( a - 2 ) ( a - 5 )}

Cancel the common factor:

a - 5

= \frac{a + 4}{a - 2}
