Answer:
10/15 8/12 14/21
Step-by-step explanation:
Use FOIL
28x² -8xy +7xy -2y²
28x² -xy -2y²
Solve for x over the real numbers:18 ° (x - 1) (x - 10 ° x) = 0
Divide both sides by 18 °:(x - 1) (x - 10 ° x) = 0
Split into two equations:x - 1 = 0 or x - 10 ° x = 0
Add 1 to both sides:x = 1 or x - 10 ° x = 0
Collect in terms of x:x = 1 or (1 - 10 °) x = 0
Divide both sides by 1 - 10 °:Answer: x = 1 or x = 0
Answer:
x = 3
Step-by-step explanation:
Given
- 3x + 2 = - 7 ( subtract 2 from both sides )
- 3x = - 9 ( divide both sides by - 3 )
x = 3
