Question

Complete the square of y=.05x^2-x+1

Answer 1

Hint: Turn \(\frac{1}{2}x^2 - x\) into \(a(x - h) + k\).

Answer 2

i think i got it x=10+/-4sqrt 5

Answer 3

\[y=\frac{ 5 }{100 }x ^{2}-x-1=\frac{ 1 }{ 20 }\left( x ^{2}-20x+100-100 \right)+1\]
\[y=\frac{ 1 }{ 20 }\left( x-10 \right)^{2}-5+1\]
\[y+4=\frac{ 1 }{ 20 }\left( x-10 \right)^{2}\]

Answer 4

correction write -1 instead of +1 and then make changes.
