Объяснение:
(2a)/(2a+3) +5/(3-2a) -(4a²+9)/(4a²-9)=(2a(3-2a)+5(2a+3))/((2a+3)(3-2a))=-8/(2a-3)
1) (2a)/(2a+3) +5/(3-2a)=(2a(3-2a)+5(2a+3))/((2a+3)(3-2a))=(6a-4a²+10a+15)/(9-4a²)=(-4a²+16a+15)/(9-4a²)
2) (-4a²+16a+15)/(9-4a²) -(4a²+9)/(4a²-9)=(-4a²+16a+15+4a²+9)/(9-4a²)=(16a+24)/(9-4a²)=(8(2a+3))/((3-2a)(3+2a))=-8/(2a-3)
