Simplify 1/5x to x/5
-9 < -x/5
Multiply both sides by 5
-9 × 5 < -x
Simplify -9 × 5 to -45
-45 < -x
Multiply both sides by -1
45 > x
Switch sides
<u>x < 45 </u>
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
