To find the prime factorization of a number, or a product of prime numbers that gives that number, we can use a number of different methods, and we can use a number of different rules. For instance, when a number can be written as a product of two primes, we have a special rule fo...

complete tasks, and make decisions like human beings—a very different approach from today’s generative AI art programs, which don’t draw from scratch (从头开始) but rather rely on databases of images. Versions of
(i) Let f(x)=2x^4+3x^3+a(x^2+x)+b.2x^2+3x-2=(2x-1)(x+2)f(1/2)=0 and f(-2)=0 since (2x-1)(x+2) is a factor of f(x).Since f(1/2)=0,2(1/2)^4+3(1/2)^3+a|(1/2)^2+(1/2)+b=01/8+3/8+a(3/4)+b=01/2+3/4a+b=02+3a+4b=0……...
