Question

Complete the square:
y=5x^2-4x+2

Answer 1

y=5x^2 -4x +2
y-2 = 5x^2 -4x

K+(y-2)/5 = x^2 -(4/5)x + K
where K= [(-4/5)/2]^2 = (-4/10)^2 = 16/100 = 4/25

(4/25) +(y-2)/5 = x^2 -(4/5)x +(16/100)
(4/5 +y -2)/5 = (x-(4/10))^2
[y-(6/5)]/5 = (x-(2/5))^2
y-(6/5)= 5(5x-2)^2
y= [5(5x-2)^2] + (6/5)

Thats the best I can do with it :)

Answer 2

thanks!

Answer 3

Id get a second opinion just to be safe :)
