1. What can you say about the value of a polynomial
when P(a)=0

The expression indicates that when polynomial P(x) is divided by divisor x - a, the remainder of the division is 0

Step-by-step explanation:

The question would be better answered if you gave option. Since there is no option, I'll answer the question generally.

Given

The above expression indicates that when polynomial P(x) is divided by divisor x - a, the remainder of the division is 0

Take for instance, the polynomial is:

And the divisor is x - 2, then P(2) = 0 because (x - 2) is a divisor of the equation.

Factorize the numerator

See that x - 2 is a divisor

To check

Set x - 2 to 0

So, we have:

it would rotate about 180 degrees.
