Divide: p^2 + 4p - 5 / p^2 + 7p + 10 * p + 4 / p - 1

Question

a) p + 2
b) p + 2 / p + 4
c) p+4 / p+2
d)2

Just need to know if my answer is right or wrong and the answer i picked was c

Answer 1

p^2+4p-5= (p-1)(p+5)
p^2+7p+10= (p+2)(p+5)

(p-1)(p+5)/(p+2)(p+5)* p+4/p-1

cross out p+5
p-1/p+2*p+4/p-1
then cross out p-1
since p+4 is the numerator it stays on top.
since p+2 is the denominator it stays at the bottom.
your result will be p+4/p+2

Answer 2
