Answer:
A = 24 / 86 = 28%
B = 43 / 92 = 47%
C = 12 / 68 = 18 %
D = 32 / 52 = 62%
Answer D
Step-by-step explanation:
If is a factor of the polynomial, it means that is a root of the polynomial.
In fact, if a polynomial has a root (i.e. ), then the polynomial is divisible by
In your case, you know that the polynomial is divisible by , so is a solution.
Let's evaluate and set it to zero:
We can check the answer: if the polynomial becomes
And we're claiming that is a root of this polynomial:
i think they are y and (x,y)
