Group and factor/undistribute
(x^2y^3-2y^3)+(-2x^2+4)
(y^3)(x^2-2)+(-2)(x^2-2)
see the (x^2-2) is common term so undistribute
(x^2-2)(y^2-2)

The best firm for the Appliance manufacturer for the repair work is Firm 2 .
In the question , 
it is given that , 
An appliance manufacturer wants to contract with a repair shop to handle authorized repairs in Indianapolis .
The acceptable range of the repair time is 50 minutes to 90 minutes.
the mean repair time for firm 1 = 74 minutes and standard deviation of 4 minutes . 
the mean repair time for firm 2 = 72 minutes and standard deviation of 5.1 minutes .
the range is calculated using the formula 
Range = Mean ± Standard Deviation 
So , for firm 1 , 
the Range = 74 ± 4 
= 74  4       and      74 - 4
 4       and      74 - 4
= 78     and   70
the range for firm 2 is 
= 72 ± 5.1
= 72  5.1      and      72 - 5.1
 5.1      and      72 - 5.1
= 7.1        and       66.9  
The second company has a lower range and it should be preferred . 
Therefore ,  The best firm for the Appliance manufacturer for the repair work is Firm 2 .
