Question

Va rog frumos.......

Answer 1

/=fractie

a)=
x(x-6)/x-6=x

b)=4(x+1)/2(x²-1)=2(x+1)/(x+1)(x-1)=2/(x-1)
c)=(x-3)(x+3)/(x+3)²=(x-3)/(x+3)
d)=x²(x-1)/x(x²-2x+1)=x(x-1)/(x-1)²=x/(x-1)
e)=a(b+1)/b²(b+1)=a/b²
f)=(2x+5)²/(2x+5)(2x-5)=(2x+5)/(2x-5)
g)=(x²-4)/(x²+4)(x²-4)=1/(x²+4)
h)=(x+4)²/(x+4)(x+5)=(x+4)/(x+5)
i)=(x+3)(x+4)/(x-3)(x+3)=(x+4)/(x-3)
j)=(x+3)(x+5)/(x+5)(x+6)=(x+3)/(x+6)
k)=(x-3)(x+5)/(x-3)(x-2)=(x+5)/(x-2)
l)=(4x+9)(x-1)/(4x-9)(4x+9)=(x-1)/(4x-9)
