So to complete the square in
ax^2+bx+c=d form
make sure a=1
subtract c from both sides
take 1/2 of b and square it
add that to both sides
factor perfect square
1x^2-1x-2=0
a=1
move c to other side
add 2 to oth sides
x^2-1x=2
take 1/2 of b and square it
1/2 of -1=-1/2
squaer it
1/4
add that to both sides
x^2-1x+1/4=2+1/4
factor left side
(x-1/2)=2+1/4
first blank is 1/2
2+1/4=8/4+1/4=9/4
blanks are
1/2 and 9/4
Answer:
I'm pretty sure it is √10, 3.12, 3.24, 31
Step-by-step explanation:
I don't know if you messed up but I got a question similar that is the length 31 in your quesion is actually 3 1/4 in my question. but i did the math and 31 is still the greatest number.
3.89 rounded to the nearest tenth is 3.9
You go to the tenths place which is 8, and then go to the number next to it. 9 is greater than 5, so you have to round up.
You regroup and get 3.9
3.9
