It should be -35 because negative interfere represent below zero
for number 1 its mixed numbers...and number 2 is The denominator
Answer:
x^3(x-4)^2
Step-by-step explanation:
x^3 is common to all three terms of f(x). Therefore,
f(x) = x^5 - 8x^4 + 16x^3 = x^3 (x^2 - 8 x + 16).
This last result can be factored further: x^3(x-4)^2
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
