The will not change
If both terms are negative then the product will be positive and
the will not change.
If is all negative then the will change to
The will change to as the product is negative
The will change to as the product is negative
Stupid inequality i can't solve, we've been told to show a certain method when solving the question which i don't understand T_T
Question
The method we are meant to use is supposed to involved these if statements (4 of them)
1. If (x+4)(3x-2) are +ve then ans is ....
2. If (x+4)(3x-2) are -ve then ans is ....
3. If (x+4) is +ve and (3x-2) is -ve then ans is ....
4. If (3x-2) is +ve and (x+4) is -ve then ans is ....
I think i can do the 1st if statement
If both denominators +ve multiply both sides by (x+4)(3x-2) which results in.
Got no idea how to do 2.3.4 someone help meee

Ok ima try the 2nd and 3rd ones then
2. If (x+4) and (3x-2) are -ve then
is multiplied on both sides by -(3x-2).-(x+4)
???? :z graphs dont intersect if both are +ve or both are -ve? :z
3. If (x+4) is +ve, (3x-2) is -ve.
is multiplied on both sides by -(3x-2).(x+4)
i think ive gone wrong arghttt
