1 answer:
Answer:
see below
Step-by-step explanation:
It is helpful to know the special forms for factoring of the difference of squares and for the square of a binomial. In any event, you can always multiply out the factors and compare the result to the list of polynomials on the left.
a² - b² = (a -b)(a +b)
(a -b)² = a² -2ab +b²
The last one requires you to collect terms before factoring.
4y² +5y -6
_____
From a "test-taking" point of view, you can see that the final constant of each of the polynomials on the left is different. This means you can make the correct choices by matching the product of constants on the right.
For example, the first one will have a constant of (-6)² = 36, matching the final constant of polynomial number 4.
