Let's factor x2−25
x2−25
The middle number is 0 and the last number is -25.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 0
Multiply together to get -25
Can you think of the two numbers?
Try 5 and -5:
5+-5 = 0
5*-5 = -25
Fill in the blanks in
(x+_)(x+_)
with 5 and -5 to get...
(x+5)(x-5)
Answer:
(x+5)(x−5)
Answer:
2/13 or 15.38%
Step-by-step explanation:
Number of Aces in a deck = 4
Number of 7s in a deck = 4
Number of cards in a deck = 52
Probability of A or 7 = (4 Aces + 4 Sevens) / 52 cards 8 cards / 52 cards
This simplifies to 2/13 or 15.38%
