a.Hp{2,3}
b.Hp{-5,3}
c.Hp{-6,2}
9.
x²-3x+2=0
Penjelasan dengan langkah-langkah:
a.x²-5x+6=0
<=>(x-2)(x-3)
<=>x-2=0 V x-3=0
x=2 x=3
jadi Hp{2,3}
b.x²+2x-15=0
<=>(x-3)(x+5)
<=>x-3=0 V x+5=0
x=3 x=-5
Jadi Hp{-5,3}
c.x²+4x-12=0
<=>(x-2)(x+6)
<=>x-2=0 V x+6=0
x=2 x=-6
Jadi Hp{-6,2}
2(x²+1)=x(x+3)
2x²+2=x²+3x
