Best ResponseYou've already chosen the best response.0factor out a (z+3) in the numerator and denominator, leaving 8/9 cancel z^2 and leave z^7 in denominator

Best ResponseYou've already chosen the best response.0z^2(8z+24)=z^2*8(z+3) (9z+27)(8z^9)=8(z+3)*8*z^9 8z^2(z+3) 8z^2(z+3) * 1/8z^9 1*1/8z^9 1/8z^9

Best ResponseYou've already chosen the best response.1get rid of 2 z's top and bottom; and the (z+3) top and bottom to get; and the 8's top to bottom to get: 1/9z^6

Best ResponseYou've already chosen the best response.1when everything is factored; you simple cancel out (its a bad term really) everything that is the same top to bottom; because they go to 1 z/z = 1 8/8 = 1 (z+3)/(z+3) = 1 so they become redundant in the equation
