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.
Answer: 18 and 32
Step-by-step explanation: The first thing you want to do is create a system of equations.
Let's use x to represent one number and y to represent the other.
So, we know that x+y=50 and x-y=14.
We can manipulate the second equation, making it x=y+14 by adding y to both sides. Then, now that we have an equivalent to x, we can plug it into the first equation to solve for y.
(y+14)+y=50
2y+14=50
2y=36
y=18
x+18=50
x=50-18
x=32
x=32, y=18
