Question

complete the square on 2x^2-4x+5, leave in vertex form.

Answer 1

wat we need to do

Answer 2

here is a snap way
vertex is when \(x=-\frac{b}{2a}=-\frac{-4}{2\times 2}=1\) and if \(x=1, y=2\times 1-4\times 1+5=3\)
to complete the square therefore, write
\[2x^2-4x+5=2(x-1)^2+3\]

Answer 3

i think now u can solve furtheer?
