10u-20/(2u+9)(u+2)(u-2), 5u^2+10u/(2u+9)(u+2)(u-2)
Step-by-step explanation:
The denominator 2u^2+13u+18 factors into (2u+9)(u+2), so multiply
10/(2u+9)(u+2) x (u-2)/(u-2)=10u-20/(2u+9)(u+2)(u-2)
The denominator 2u^2+5u-18 factors into (2u+9)(u-2), so multiply
5u/(2u+9)((u-2) x (u+2)/(u+2)=5u^2+10u/2u+9)(u+2)(u-2)
