Answer:-m or m+3
Step-by-step explanation:
Applying difference of two squares
⇒()=(x+m)(x-m)
Substituting this for ()
Factorising -3x-3m=-3(x+m)
(x+m)(x-m)-3(x+m)=0
since we have double (x+m),we'll pick one
⇒(x+m)=0
or (x-m-3)=0
⇒x=-m or x= m+3
Answer:
- 3 < y
- y < -2
Step-by-step explanation:
1. -2y+7 < 1
Add 2y-1:
6 < 2y
Divide by 2:
3 < y
__
2. 4y +3 < -5
Subtract 3:
4y < -8
Divide by 4:
y < -2
_____
These are graphed on the number line with open circles because y=-2 and y=3 are not part of the solution set.
