Question
Hello please help me with these questions they are really small but there is certain way you must do it I will put an example in the photos. Numbers 1,3,5 and 9 please they are really short the first picture is the example and the second the questions it is quadratic Inequalities. There must be a drawing

EXAMPLE 12
Solve for x:
(b)
3x2 -2.x S1
(a)
-x² +5x+6<0
Solution
-x² +5x+6<0
:x-5x-6>0
(a)
+-1 and change direction of inequality
x²- 5x-6=0
(x-6)(x+1)=0
x=6 or x=-1
Critical Values:
050
>0
>0
<0
Final Solution: x<-1
or x>6
abon's
3x - 2x<1
3x2 – 2x-1<0
(b)
Critical Values:
3x2 - 2x-1=0
(3x+1)(x-1)= 0
1
or
x=--
x= 1
>0
>0
Final Solution:
13
