Answer:
4/13
Step-by-step explanation:
-6/5x - 6 + 2=4x - 28/5
-6/5x - 4=4x - 28/5
-6/5x - 4x= -28/5 + 4 (multiply each side by 5)
-6x - 20x= -28+20
-26x= -8 (divide each side by 26)
-x= -8/26 (multiply each side by -1)
x= 8/26 (reduce)
x= 4/13
Answer:
f(x) = x^3 - x^2 -2x
Step-by-step explanation:
If x = a is a zero of a polynomial, then x-a is a factor of the polynomial. Given the factors of a polynomial, the polynomial can be obtained by multiplying the factors.
The factors of the given polynomial are;
x - 2
x + 1
x
Multiplying the first two factors;
(x-2)(x+1) = x^2 + x -2x -2
= x^2 -x -2
We finally multiply this result by x to obtain our polynomial;
f(x) = x ( x^2 -x -2)
= x^3 - x^2 -2x
which is a cubic polynomial since it has 3 roots.
