When completing the square with $ y=x^2+10x+12$, What is the number that will be added and subtracted in???
120
25 bc when you take $1/2$ of 10 then squared it it = 25
6 bc it is $1/2$ of 12
5 bc it is $1/2$ of 10

When completing the square with $f(x)=x^2 +16x−46$. Which of the following represents the next step : Take the middle # (16) divide by 2 (which is 8) then square it (so it is 64), add and subtract 64 .......
120
$f(x)=(x^2 +16x+8)+(-8−46)$
$f(x)=(x^2 +16x+64)$+(-64−46)
$f(x)=(x^2 +16x-64)+(-64−46)$

Rewrite by completing the square (same as last question) $f(x)=x^2+18x+5$ Ask yourself what # am I adding /subtracting ( The square of half of the middle #) and by combining the - of that # with the given number what is left?
120
$f(x)=(x+9)^2-76$
$f(x)=(x+18)^2-76$
$f(x)=(x-76)^2-81$
$f(x)=(x+9)^2+5
