Consider the quadratic equation
y=9x%5E2-8+x
Complete the square to express the quadratic in standard form
y=a%28x-h%29%5E2+%2Bk
y=9x%5E2-8x....factor out 9
y=9%28x%5E2-%288%2F9%29x%29
y=9%28x%5E2-%288%2F9%29x%2Bb%5E2%29-9b%5E2.....b=%288%2F9%29%2F2=%284%2F9%29
y=9%28x%5E2-%288%2F9%29x%2B%284%2F9%29%5E2%29-9%284%2F9%29%5E2
y=9%28x-4%2F9%29%5E2-16%2F9
so,
a=9
h+=4%2F9
k+=-16%2F9
