Factor Completely: x2 + 16 (x + 4)(x - 4) (x - 4)(x - 4) (x + 4)(x + 4) Prime

1 answer:

7 0

I think the correct answer from the choices listed above is the last option.The expression x^2 + 16 is a prime expression which cannot be further simplified over the real numbers<span>. But when considering the complex numbers, the factor would be:

</span><span>(x + 4i)(x - 4i)</span>

Which of the following represents the factored form of f(x) = x3 − 81x?

sladkih [1.3K]

You're original equation has a -81, so the factored form will have to have a positive and negative multiplying one another to achieve that...

f(x) = x(x + 9)(x - 9)
