Question

Simplify... (q^2-6q-7)/(q^2-4q-21)-(q^2+4q+3)/(q^2+2q+1)
i need help with the steps. please

Answer 1

\[\frac{ q^2-6q-7 }{ q^2-4q-21 }-\frac{ q^2+4q+3 }{ q^2+2q+1 }\]

Answer 2

can somebody help show me the steps to this problem

Answer 3

first part on the right can be factored to (q -7) ( q+1) / (q-7)(q+3) so it will result in to ( q+1 /q+3

Answer 4

the second part ( q +1)(q+3) / (q+1) (q+1) will be q +3 / q+ 1

Answer 5

now its easy to subtract

Answer 6

:)

Answer 7

ok thank you
