Final answer:
To write a binomial as a product of its greatest common factor and another binomial, factor out the greatest common factor.
Step-by-step explanation:
(a) To write the binomial 8x - 40 as a product of its greatest common factor and another binomial, start by factoring out the greatest common factor, which is 8. This gives us 8(x - 5).
(b) To write the binomial 6 - 18 as a product of its greatest common factor and another binomial, start by factoring out the greatest common factor, which is 6. This gives us 6(1 - 3).
