X2+16 is the prime <span>polynomial.
x2+16 is the only </span><span>polynomial that couldn't be factored out anymore
x2-36 --> (x-6)(x+6)
x2-7x+12 --> (x-3)(x-4)
x2-x-20 --> (x+5)(x-4)</span>
Answer:
93 days between them. 93 is a multiple of 7, so they will fall on the same day.
Step-by-step explanation:
