25 = 5*5 and 9 = 3*3, which we can exploit to write
so that this expression is actually a difference of squares. We can factorize this to get
and given that 
, we divide both sides by this to get
Answer:
The solution set for the inequality is the interval (-4, 5)
Step-by-step explanation:
-8 < 8 + 4x < 28
Subtracting 8:
-8 -8 < 8 + 4x - 8 < 28 - 8
-16 < 4x < 20
Dividing by 4:
-16/4 < 4x/4 < 20/4
-4 < x < 5
x ∈ (-4, 5)
(8x-5)(2x+1)
Check: 16x^2+8x-10x-5
16x^2-2x-5
The answer is 2/3
64/96 to 32/48 to 16/24 to 8/12 to 4/6 to 2/3..........(64/96 in simplest form becomes 2/3)
