Me simplify this rational expression

1 (x+1)

3(x+2)

Step-by-step explanation:

4(x^2-1)

12(x+2) (x-1)

Factor the numerator

4(x-1) (x+1)

12(x+2) (x-1)

Cancel the x-1 from both the numerator and denominator

4 (x+1)

12(x+2)

Both 4 and 12 can be divided by 4

1 (x+1)

3(x+2)

This is as simplified as it can go

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)

step-by-step explanation:
