Could someone help explain these problems? They've both stumped me.
(z^2-11z+24)/(5z^2-25z-120)
(48-3z^2)/(z^2-7z+12)
Not sure how to use the <math> coding...
Thanks so much
So I've got $\displaystyle (z-8)(z-3)/5(z-8)(z+3)$ on the first one. Cancel out those z-8's cancel out so it leaves me with $\displaystyle (z-3)/(5z+3)$?
And on the second: $\displaystyle 3(z-4)(z+4))/(z-3)(z-4)$. Cancel out the z-4's, I get $\displaystyle (3z+4)/(z-3)$
Are those correct?
