Hello!
Answer:
|2x - 5| = 4
Solve for the negative and positive expressions:
2x - 5 = 4
2x = 9
x = 9/2
------------
-(2x - 5) = 4
-2x + 5 = 4
-2x = -1
x = 1/2.
Therefore, the solutions are x = 1/2 and 9/2.
well, rational = fractional, namely something you can write as a fraction, well, anything between -1 and -2 is just less than -1 so
5p(2p-3)(p+7)=0
10p-15 p +7 =0
10p+p=0+15-7
11p =8
11p=8
p=8/11
