Answer:

• ac = 24
• b = 11
• (x +8)(x +3)

Step-by-step explanation:

In your expression, you have ...

  a = 1

  b = 11

  c = 24

Then ac = (1)(24) = 24, and b = 11. The chart looks like the attached.

The numbers on the side have a sum equal to the bottom number (11) and a produce equal to the top number (24). These are the constants in the binomial factors, so the factored form is ...

  (x +8)(x +3) . . . . equivalent factored form

Answer 2

The value of ac is

✔ 24

.

The value of b is

✔ 11

.

The equivalent factored form of the polynomial is

✔ (x + 3)(x + 8)
