Multiply the coefficient of the first term by the constant 1 • -31 = -31
Find two factors of -31 whose sum equals the coefficient of the middle term, which is -2 .
-31 + 1 = -30
-1 + 31 = 30
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Answer:

5. The graph is a negative on the Entire interval -4<x<6
Answer:
1)38.5
2)39
Step-by-step explanation:
median: put the numbers smallest to biggest the cross out the number from both sides one by one until you get to the middle if there are two numbers in the middle the add them and divide it by 2
mean: add them all up and then divide by how many numbers there are in total
