Wich is a factor of x^2+ 5x-24?
1 answer:
Answer:
(x−3)(x+8)
Step-by-step explanation:
Let's factor x2+5x−24
x2+5x−24
The middle number is 5 and the last number is -24.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 5
Multiply together to get -24
Can you think of the two numbers?
Try -3 and 8:
-3+8 = 5
-3*8 = -24
Fill in the blanks in
(x+_)(x+_)
with -3 and 8 to get...
(x-3)(x+8)
Answer:
(x−3)(x+8)
