M² +4m - 2

What is the answer

Doesn't factor

Step-by-step explanation:

Factor

___________

Assuming you want m factored, you can follow a rule I use. Find two numbers that multiply to c (in this case -2), and use the same two numbers to add them to equal b (in this case 4).

m^2 + 4m - 2

There are no numbers that can do this, therefore this is unfactorable.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
