Obtaining the Zeros of the Polynomial
To obtain the zeros of the polynomial root 3x^2-8x 4 root 3, we need to set the polynomial equal to zero and solve for x.
3x^2-8x+4root3=0
Using the quadratic formula, we can find the values of x that make the equation true.
x = [8 ± sqrt(64 - 48)]/6
x = [8 ± 4sqrt(2)]/6
x = (4 ± 2sqrt(2))/3
Therefore, the zeros of the polynomial are (4 + 2sqrt(2))/3 and (4 - 2sqrt(2))/3.
Verifying the Relation between Zeros and Coefficients
The relation between the zeros and coefficients of a quadratic equation is given by the following formulas:
- Sum of roots = -b/a
- Product of roots = c/a
where a, b, and c are the coefficients of the quadratic equation ax^2 + bx + c = 0.
For the given polynomial, a = 3, b = -8, and c = 4root3. Therefore, we have:
- Sum of roots = -(-8)/3 = 8/3
- Product of roots = (4root3)/3
We can verify these values using the zeros we obtained earlier:
- Sum of roots = (4 + 2sqrt(2))/3 + (4 - 2sqrt(2))/3 = 8/3
- Product of roots = [(4 + 2sqrt(2))/3][(4 - 2sqrt(2))/3] = (16 - 8)/9 = 8/9 * 3sqrt(2) = (4root3)/3
Therefore, we have verified that the relation between the zeros and coefficients holds for the given polynomial.
