Answer 1

Answer:

Consider the form

x

2

+

b

x

+

c

. Find a pair of integers whose product is

c

and whose sum is

b

. In this case, whose product is

−

24

and whose sum is

5

.

−

3

,

8

Write the factored form using these integers.

Step-by-step explanation:

(x-3) (x plus 8)

Answer 2

Answer:

$- {x}^{2} + 5x + 24 \\ - {x}^{2} + 8x - 3x + 24 \\ - x(x - 8) - 3(x - 8) \\ (x - 8)( - x - 3)$

this will be the solution
