How do you multiply and simplify #\frac { 6- 2t } { t ^ { 2} + 4t + 4} \cdot \frac { t ^ { 3} + 2t ^ { 2} } { t ^ { 9} - 9t ^ { 6} }#?

1 Answer

#(2t^2(3-t))/(t^6(t+2)(t^3-9))#

Explanation:

#(6-2t)/(t^2+4t+4)*(t^3+2t^2)/(t^9-9t^6)#

#=(3(2-t))/((t+2)cancel((t+2)))*(t^2cancel((t+2)))/(t^6(t^3-9))#

#=(2t^2(3-t))/(t^6(t+2)(t^3-9))#

#=(2(3-t))/(t^(6-2)(t+2)(t^3-9))#

#=(2(3-t))/(t^(4)(t+2)(t^3-9))#
