Answer:
-x^2 - 11x -30
Step-by-step explanation:
Solve using foiling. Ignore the -1 to begin with and just look at the part in parenthesis. Do x from the first parenthesis times the stuff in the second parenthesis.
ie: x(x) and x(6)
ie: x^2 + 6x
Then do the 5 times the things in the second parenthesis.
ie: 5(x) and 5(6)
ie: 5x + 30
Then add what you got from multiplying the first value to what you got from multiplying the second.
ie: x^2 + 11x + 30
This is a trinomial because it has three different variables. Now change all the signs to negative because of the -1 out front.
ie: -x^2 - 11x -30
2:4
4:8
5:10
200:400
This is because if you divide each ratio you get 1/2

D is you answer Have a wonderful day !
Negative times negative is positive.
Positive times positive is positive.
Negative times positive is negative.
(-3.8)(-5.7) gives you a positive product then it is + times (-1.4) which gives you a negative product.
