Answer: y=3x+1
Step-by-step explanation:
First find slope using formula
m= y2–y1/x2–x1
m= 4– (—2)/ 1— (—1)
m= 3
So,
y= mx+b
y=3x+b. Using (1,4) plug into equation of a line
4= 3(1)+b
4 – 3= b
1= b. So,
y=3x+1
ANSWER
![{x}^{3} - {y}^{3} = (x - y)[ {x}^{2} + xy + {y}^{2}]](https://tex.z-dn.net/?f=%7Bx%7D%5E%7B3%7D%20%20%20-%20%20%7By%7D%5E%7B3%7D%20%20%3D%20%28x%20-%20y%29%5B%20%7Bx%7D%5E%7B2%7D%20%20%2B%20xy%20%2B%20%20%7By%7D%5E%7B2%7D%5D)
EXPLANATION
We want to factor:
completely.
Recall from binomial theorem that:
We make x³-y³ the subject to get:
We now factor the right hand side to get;
We factor further to get,
![{x}^{3} - {y}^{3} = (x - y)[( {x - y)}^{2} + 3 {x} y]](https://tex.z-dn.net/?f=%7Bx%7D%5E%7B3%7D%20%20%20-%20%20%7By%7D%5E%7B3%7D%20%20%3D%20%28x%20-%20y%29%5B%28%20%7Bx%20-%20y%29%7D%5E%7B2%7D%20%20%2B%203%20%7Bx%7D%20y%5D)
![{x}^{3} - {y}^{3} = (x - y)[ {x}^{2} - 2xy + {y}^{2} + 3 {x} y]](https://tex.z-dn.net/?f=%7Bx%7D%5E%7B3%7D%20%20%20-%20%20%7By%7D%5E%7B3%7D%20%20%3D%20%28x%20-%20y%29%5B%20%7Bx%7D%5E%7B2%7D%20-%202xy%20%2B%20%20%7By%7D%5E%7B2%7D%20%20%2B%203%20%7Bx%7D%20y%5D)
This finally simplifies to:
