Question 607049: Use the rational zeros theorem to find all the zeros of the polynomial d(x)= 4X^3-4X^2-7X-2. Use the zeros to factor d over the real number. Be sure to state all the potential rational zeros as well Answer by lwsshak3(11628) (Show Source):
You can put this solution on YOUR website! Use the rational zeros theorem to find all the zeros of the polynomial d(x)= 4X^3-4X^2-7X-2. Use the zeros to factor d over the real number.

...0...|....4......-4..... -7....-2
...1...|....4.......0......-7....-9
...2...|....4.......4...... 1......0 (2 is a zero)
d(x)=(x-2)(4x^2+4x+1)
d(x)=(x-2)(2x+1)^2
zeros are: 2 and -1/2 (multi 2)

note: I don't understand what "factor d over the real number" means.
