Answer:
Step-by-step explanation:
Start by taking everything out of the parentheses:
![3x^2-2xy-2y^2-x^2-(-3xy)-(y^2)](https://tex.z-dn.net/?f=3x%5E2-2xy-2y%5E2-x%5E2-%28-3xy%29-%28y%5E2%29)
Note two negatives make a positive:
![3x^2-2xy-2y^2-x^2+3xy-y^2](https://tex.z-dn.net/?f=3x%5E2-2xy-2y%5E2-x%5E2%2B3xy-y%5E2)
Combine like terms:
![3x^2-x^2-2xy+3xy-2y^2-y^2](https://tex.z-dn.net/?f=3x%5E2-x%5E2-2xy%2B3xy-2y%5E2-y%5E2)
Simplify
![2x^2+xy-3y^2](https://tex.z-dn.net/?f=2x%5E2%2Bxy-3y%5E2)
Answer:
21
Step-by-step explanation:
3/(x-3) = 8/(2x+6)
or, 3(2x+6) = 8(x-3) ( by cross multiplication)
or, 6x + 18 = 8x - 24
or, 8x - 6x = 24 + 18
or, 2x = 42
or, x = 42/2
