Factoring trinomials, mind me out?

(x - 13)(x + 3)

Step-by-step explanation:

The square term is just x^2 with no coefficient.

Write:

(x    )(x    )

Now you need two numbers that multiply to -39 and add to -10.

39 = 3 * 13

The numbers you need are -13 and 3 since -13 * 3 = -39, and -13 + 3 = -10.

Now write the numbers -13 and +3 in the parentheses.

(x - 13)(x + 3)

could you give more information?

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.
