Which of the following statements best describes the "grouping method" of factoring trinomials?
Choose the correct answer below.
O A. The grouping method of factoring trinomials involves separating the first and last terms of the trinomial into respective factors, and then factoring by
grouping
OB. The grouping method of factoring trinomials involves rewriting the bx term into the factors that fit the particular trinomial, and factoring these four terms using
grouping
OC. The grouping method of factoring trinomials involves factoring out the common factor.

Explanation:

The description may be better explained by applying it to an example.

Example:

          Two numbers which add up - 1 and multipled are - 30. Those numbers are - 6 and + 5, because -6 + 5 = - 1 and (-6) × (+5) = -30.

           Hence, the two terms are -6x and 5x, and the expression rewritten is:

            x² - 6x + 5x - 30

            (x² - 6x) + (5x - 30)

            x(x - 6) + 5(x - 6)

            (x - 6) (x + 5)

Hence, the factored trinomial is (x - 6) (x + 5)

answer: 25 is the correct answer

step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
