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:
x=6
Step-by-step explanation:
Because these lines are parallel, that means these angles are congruent, so you can set up an equation because they are equal to each other.
110=19x-4
add 4 to both sides
114=19x
and divide by 19
6=x
or
x=6
When you divide a number by two, you find the number that if you add it to itself, become the original number.
When you square root a number, you find the smaller number that becomes the bigger number if you multiply it by itself.
For sixteen, if you divide it by two, you get 8, while if you square root it, it becomes 4.
Answer:
x intercepts: (-3, 0)
y intercepts: (None)
Step-by-step explanation:
