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
THE NUMBER WOULD BE -160. One-fourth of -160 is -40, and -40 decreased by 10 would be -150, because ( -40 - 10 = -50. ) It's quite simple. All you had to do was find a number that, when multiplied by 4, would equal a number that when decreased by 10 would be -50.
