Answer:
4/5
Step-by-step explanation:
- -18/2 = -9, and integer
- √9 = 3, an integer
- 0, an integer
- 4/5, irreducible fraction; not an integer
Assuming that your question is (x-1)(x+2) = [5(x-1)]/x-1
On the right side, the x-1's will cancel out, leaving you with (x-1)(x+2) = 5
expand the left side, giving you x^2 + x -2 = 5
which goes to x^2 +x -7 = 0
the possible values for x are 2.93 and -3.93. I don't think this was your question, so I'll do the other possible question that you might have been asking.
(x-1)(x+2) = 5(x-1)
divide by x-1 on both sides, leaving you with x+2=5
x+2=5
x=5-3
x=3
Answer:
x=9
Step-by-step explanation:
8(2x-6)=96
2x-6=96/8
2x-6=12
2x=12+6
2x=18
x=18/2
x=9
