Not enough information given
6a+8b; when a variable is next to a coefficient then that means they are multiplying each other, we just don't know what a or b is.
Given,
The expression is,

If x- 3 is the factor of the given polynomial function, then on substituting the value of x = 3 in the polynomial function, it become zero.
Thus subsituting the value of x in the polynomial,

Here, the obtained value of polynomial is 0.
Hence, x-3 is a factor of the given polynomial.
Thus, option A(true) is correct.
