-1/4(x^2+4x)+1/4 what to add and subtract ?
3psilon
  • 3psilon
subtract 1/4

we add and subtract the square of half of co-efficient of x so here, what is half of 4 ?

and its square ?
3psilon
  • 3psilon
4
hartnn
  • hartnn
so what will u add and subtract ?
3psilon
  • 3psilon
Do you subtract the square?
hartnn
  • hartnn
u add and subtract the 4 like this: -1/4(x^2+4x+4 -4)+1/4 can u go ahead ?

y-1/4 +4 = -1/4(x^2+4x -4)
hartnn
  • hartnn
y-1/4 -4(1/4) = -1/4(x^2+4x +4)
3psilon
  • 3psilon
why -4(1/4) on the left???
hartnn
  • hartnn
y=-1/4(x^2+4x+4 -4)+1/4 = -1/4 (x^2+4x+4) -1/4 (-4) +1/4 y-1/4 -1/4(4) = -1/4(x^2+4x+4) confusing ?
3psilon
  • 3psilon
why did you not add it to both sides? why subtract? it says -1/4(-4)
3psilon
  • 3psilon
Ohh I see it now
3psilon
  • 3psilon
Wow thank you so much
hartnn
  • hartnn
u can continue to get the vertex form, right ?
3psilon
  • 3psilon
yess It is quite easy now. Thank you so much :) I can sleep now haha
