40 and 14, sorry
OpenStudy (anonymous):
x^2+26x-560=(x-40)(x+14)
x=40 or -14
-14 is not an age so ur sister is 40
hero (hero):
beat you again jah
hero (hero):

WHATS THE ANSWER , SHOW WORK hahahaha ??
hero (hero):
If you don't know quad equations, can't help you
OpenStudy (anonymous):
x=sisters age
x+26=cousins age
(x)(x+26)=560
x^2+26x=560
x^2+26x-560=0
solve for x gives ur sis age
(x+40)(x-14)=0
x=14 or -40 since -40 is not an age ur sis is 14
now find cousins age
x+26
x=14
so
14+26=40
ur cuz is 40
