f(x)=-8x²+5x+1=

f(x)=-8(x^2-5/8x)+1

f(x)=+?=-8(x^2-5/8x+?)+1

f(x)+?=-8(x^2-5/8x+25/256)+1

f(x)-8×25/256=-8(2x-5/8x+25/256)+1

f(x)-25/32=-8(x^2-5/8x+25/256)+1

f(x)-25/32=-8(x-25/16)^2 +1

f(x)=-8(x-5/16)^2 +1 +25/32

f(x)=-8(x-5/16)^2+57/32

f(x)=12x³+7x²-3x-2=

f(0)=12×0^3+7×0^2-3×0-2

f(0)=12×0+7×0^2-3×0-2

f(0=)12×0+7×0-3×0-2

f(0)=12×0+7×0-0-2

f(x)=12×0+7×0-2

f(0)=0+7×0-2

f(0)=0+0-2

f(0)=0-2

f(0)=-2

f(x)=-6x²+4x+1=

f(x)=-6(x^2-2/3x)+1

f(x)+?=-6(x^2-2/3x+?)+1

f(x)+?=-6(x^2-2/3x+1/9)+1

f(x)-6x1/9=-6(x^2-2/3x+1/9)+1

f(x)-2/3=-6(x^2-2/3x+1/9)+1

f(x)-2/3=-6(x-1/3)^2+1

f(x)=-6(x-1/3)^2 +1+2/3

f(x)=-6(x-1/3)^2+5/3

g(x)=3x²-6x+3=

g(x)=3(x^2-2x)+3

g(x)+?=3(x^2-2x+?)+3

g(x)+?=3(x^2-2x+1)+3

g(x)+3×1=3(x^2-2x+1)+3

g(x)+3=3(x^2-2x+1)+3

g(x)+3=3(x-1)^2+3

g(x)=3(x-1)^2+3-3

g(x)=3(x-1)^2=0

g(x)=3(x-1)^2

espero te sirva y sea de gran ayuda
