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)
* parenthesis tell you to multiply whatever is outside them by whatever is inside them, so let’s do that!
All we need is a calculator !!
1. 0.3(p) - 0.3(3)
0.3p - 0.9
2. 1.2(0.3x) - 1.2(1.4)
0.36x - 1.68
3. -3(2x) - 3(5)
-6x - 15
4. -7(2k) - 7(-h)
-14k + 7h
5. -1/2(6x) - 1/2( -1/3)
-3x + 1/6
6. -3(0.2m) - 3(5)
-0.6m - 15
7. -0.6(0.4y) - 0.6(-1)
-.24y + 0.6
* remember that when you multiply to negatives, it equals a positive!!
Hope I helped :)
