Answer: A. negative 3 over 5 is located on the right of −2
Step-by-step explanation:
On a number line, the greater numbers are to the right and the smaller numbers are to the left.
For this case we must simplify the following expression:
We apply distributive property:
To multiply powers of the same base, the same base is placed and the exponents are added.
We simplify similar terms:
Finally we have:

If P(x) = ax^4 + bx^3 + cx^2 + dx + e has roots at x = 1, 2, 3, 4, then
0 = a + b + c + d + e0 = 16 a + 8b + 4c + 2d + e0 = 81 a + 27b + 9c + 3d + e0 = 256 a + 64 b + 16c + 4d + e
P(0) = 48 e = 48
There are five equations, five unknowns, hence the linear equations can be solved. a is equal to 2, b is equal to -20, c is equal to 70, d is equal to -100 and e is equal to 48
