Consider the quadratic equation
+y=x%5E2%2B8x+%2B+18
Complete the square to express the quadratic in standard form
y=a%28x-h%29%5E2+%2Bk
+y=%28x%5E2%2B8x%2Bb%5E2%29-b%5E2+%2B+18........b=8%2F2=4
+y=%28x%5E2%2B8x%2B4%5E2%29-4%5E2+%2B+18
+y=%28x%2B4%29%5E2-16+%2B+18
+y=%28x%2B4%29%5E2+%2B2

a=1
h+=-4
k+=2
