已知b-1/2a²=0,化简:3ab+3b/a²+b已知b -1/2a² = 化简:3ab +3b/a²+b

已知b-1/2a²=0,化简:3ab+3b/a²+b已知b -1/2a² = 化简:3ab +3b/a²+b
已知b-1/2a²=0,化简:3ab+3b/a²+b
已知b -1/2a² = 化简:3ab +3b/a²+b

已知b-1/2a²=0,化简:3ab+3b/a²+b已知b -1/2a² = 化简:3ab +3b/a²+b
b -1/2a² = 0
b=1/2a²
a²=2b
(3ab +3b)/(a²+b )
=3b(a+1)/(2b+b)
=3b(a+1)/3b
=a+1

b -1/2a² = 0,
b =1/2a²
3ab +3b/a²+b
=3b(a+1)/(a²+b)
=3/2*a²(a+1)/(3/2a²)
=(a+1).
