The first step in the process for factoring the trinomial x^2-5x-36 is to:
a. find the sum of the factors of 5
b. find the sum of the factors of 36
c. list all the factors of the 5
d. list all the factors of 36

D. List all the factors of 36.

Step-by-step explanation:

We are given the following information in the question:

We have to factorize the above expression.

To do so, we use the technique of splitting the middle term.

The first step in finding these factors is to find a pair of factors whose sum is -5 and whose product is -36.

Thus, we need to list all the factors of 36 and then find the factors of -36 and find a pair such that the sum of factors is -5.

The factors could be find in the following manner:

The factors are (x+4) and (x-9).

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
