espero te sirva

me puedes por mi coronita pliss?

Explicación paso a paso:

y=x²-x-2

y+?=x²-x+?-2

y+?=x²-x+1/4-2

y+1/4=x²-x+1/4-2

y+1/4=(x-1/2)²-2

y=(x-1/2)²-2-1/4

y=(x-1/2)-9/4

y(x-1/2)²-9/4

y=2x²+4x-5/2

y=2(x²+2x)-5/2

y+?=2(x²+2x+?)-5/2

y+?=2(x²+2x+1)-5/2

y+2×1=2(x²+2x+1)-5/2

y+2=2(x²+2x+1)-5/2

y+2=2(x+1)²-5/2

y=2(x+1)²-5/2-2

y=2(x+1)²-9/2

y=x²+6x+9

y+?=x²+6x+?+9

y+?=x²+6x+9+9

y+9=x²+6x+9+9

y+9=(x+3)²+9

y=(x+3)²+9-9

y=(x+3)²+0

y=(x+3)²

y=2x²+x-3

y=2(x²+1/2x)-3

y+?=2(x²+1/2+?)-3

y+?=2(x²+1/2+1/16)-3

y+2×1/16=2(x²+1/2+1/16)-3

y+1/8=2(x²+1/2+1/16)-3

y+1/8=2(x+1/4)²-3

y=2(x+1/4)²-3-1/8

y=2(x+1/4)²-25/8
