A polynomial function P(x) with rational coefficients has the roots sqrt 2 and - sqrt 13. Find two additional roots.

bixtya [17]

Answer:

$-\sqrt{2}$ and $\sqrt{13}$

Step-by-step explanation:

Given a polynomial with rational coefficients, its irrational and complex roots would occur in conjugate pairs.

For example, if the roots of a polynomial are 2 + $\sqrt{3}$ , 3 and 4 - 3i, then 2 - $\sqrt{3}$ , and 4 + 3i are also roots of the polynomial.

Therefore, since the given polynomial has rational coefficients and some of its roots are , $\sqrt{2}$ and - $\sqrt{13}$ , then - $\sqrt{2}$ and $\sqrt{13}$ are also roots of the polynomial.

Formular for straight line: y = mx + c
Where
m = slope
c = constant

$m= { \frac{y_1-y_2}{x_1-x_2} } \\ m= { \frac{-1 - 0}{0 - 3 } } \\ m= { \frac{-1}{-3} } \\ m= { \frac{1}{3} }$

-1 = 1/3(0) + c
c = -1
y = 1/3x - 1
