PLEASE HELP!!! What is the product in simplest form? State any restrictions on the variable. z^2/z+1 times z^2+3z+2/z^2+3z
Question
Answer:
z^2 - z^2+3z+2
-------------------------
z+1 z(z+3)
z(z+1)(z+3) is the lcd
z^2(z^2+3z)- (z+2)(z+1)(z+1)
--------------------------------------...
z(z+1)(z+3)
z^4+3z^3- (z^2+3z+2)(z+1)
z^2+3z+2
z+1
----------------
z^2+3z+2
z^3+3z^2+2z
-------------------------
z^3+4z^2+5z+2
z^4+3z^3-z^3-4z^2-5z-2
ans . z^4+2z^3-4z^2-5z-2
-------------------------------------
z(z+1)(z+3)
z Γ’β° 0, -1 or -3
