Question

Find the roots of the factored polynomial.

Answer 1

Answer:

x = {- 4, 4}

Step-by-step explanation:

factored polynomial is: (x–4)(x+4)

Let (x–4)(x+4) = 0

$\therefore \: (x - 4)= 0 \: or \: (x+4) = 0 \\ \therefore \:x = 4 \: \: or \: \: x = - 4 \\ \therefore \:x = \{ - 4, \: \: 4 \} \\ are \: the \: required \: roots.$
