Question

Va rog frumosss, imi mai trebuie punctele a si c ... Va roggg

Answer 1

2x²-5x+3/x²+x-6>0⇒2x²-5x+3>0(x²+x-6)⇒2x²-5x+3>0
a=2
b=-5
c=3
Δ=b²-4ac⇒Δ=(-5)²-4x2x3⇒Δ=25-24⇒Δ=1
x1x2=-b+-√Δ/2a
x1=5+1/4⇒6/4⇒3/2
x2=5-1/4⇒4/4⇒1

c)x²-x/x²+x+5≥0⇒x²-x≥0(x²+x+5)⇒x²-x≥0
a=1
b=-1
c=0
Δ=b²-4ac⇒Δ=(-1)²-4×1×0⇒Δ=1+0⇒Δ=1
x1x2=-b+-√Δ/2a
x1=-1+1/2⇒0/2⇒0
x2=-1-1/2⇒-2/2⇒-1
