Complete the square to put the equation into vertex form.
y=9x%5E2-9x%2B1
y=9%28x%5E2-x%29%2B1
y=9%28x%5E2-x%2B1%2F4%29%2B1-9%281%2F4%29
y=9%28x-1%2F2%29%5E2%2B4%2F4-9%2F4
highlight%28y=9%28x-1%2F2%29%5E2-5%2F4%29

Write the expression 9x%5E2-9x%2B1 in the form of a%28x%2Bb%29%5E2%2Bc. where a, b and c are real numbers
----------
9x%5E2-9x%2B1
= 9%28x%5E2+-+x%29+%2B+1
= 9%28x%5E2+-+x+%2B+1%2F4%29+%2B+1+-+9%2F4
= 9%28x+-+1%2F2%29%5E2+-+5%2F4
