Answer:

m = - 3

Step-by-step explanation:

$\frac{m}{3} - \frac{2m}{5} = \frac{1}{5}$

It is much easier to work with whole numbers, compared to fractions, hence one should remove the denominator of the fraction. This can be done by multiplying by the LCM (least common multiple). In this case, it is fairly obvious that the LCM of 3 and 5 is 15. Therefore multiply the entire equation by 15.

$15*\frac{m}{3} - 15*\frac{2m}{5}=15*\frac{1}{5}$

Simplify

$5m-6m=3$

$-m=3\\m=-3$

Given:

The polynomial function is

$F(x)=4x^3-6x^2+9x+10$

To find:

The possible roots of the given polynomial using rational root theorem.

Solution:

According to the rational root theorem, all the rational roots and in the form of $\dfrac{p}{q}$ , where, p is a factor of constant and q is the factor of leading coefficient.
