For a polynomial p(x), if p(a) = 0, then which of the following must be a factor of p(x)? x^2 + a

x — а

x + a

x^2 - a

x _ a

Step-by-step explanation:

because if a is zero .then they should be subtraction

1 1/5

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
