The roots of the polynomial for this case will be x1 = 6, x2 = -6, x3 = 4, x4 = -4.You can solve the polynomial using the resolver after making the variable change u = x ^ 2 so that you have a second degree polynomial. Then return the change to find the missing roots. Attached solution.
Answer:
(3) 2(3x - 5)(3x + 5)
Step-by-step explanation:

Distribute the “-3” to both n&-3 —> -3n+9 then your left with -5 and subtract 9-5
-3n+4
