Answer:
? = 16
Step-by-step explanation:
x2 - 8x + ? = 42 + ?
1. Take the coefficient of the middle term 8x, which is 8 and divide it by 2. . Then square it
2. Take 16 and add it to both sides:
2. Take half of the coefficient 8 that you divided by 2, which is 4 and insert 4 into the equation
3. ? = 16
B.
if you plug in the points you get for the first one
3(3) - (4/(-8)) = 9+2 = 11
and the second
3(4) - (4/4) = 12-1 = 11
