二次函数配方:Y=3X²-2X+4
二次函数配方:Y=3X²-2X+4
二次函数配方:Y=3X²-2X+4
Y=3X²-2X+4
=3(X²-2/3X+1/9)-1/3+4
=3(X-1/3)²+11/3
y=3(x²-2x/3)+4
=3(x²-2x/3+1/9)+11/3
=3(x-1/3)²+11/3
Y=3X²-2X+4
=3(x²-2x/3)+4
=3(x²-2/3x+1/9)-1/3+4
=3(x-1/3)²+11/3
y=3(x²-2x/3)+4
=3(x²-2x/3+1/9-1/9)+4
=3(x²-2x/3+1/9)-1/3+4
=3(x-1/3)²+11/3
y=(3x-1)(x-1)+5
y=3(x2-2/3x)+4=3(x2-2/3x+1/9)+4-1/3=3(x-1/3)2+11/3
