Answer:

Step-by-step explanation:

If the solution of the system of equations is {(x, y): x - y = 4} - infinitely many solutions, then this system is consistent and dependent.

x - 3y = 4 <em>multiply both sides by 2</em>

2x - 6y = 8

Therefore Q = -6

Express as a trinomial. (3x+3)(2x−4)

Artyom0805 [142]

Use the FOIL method: First, Outside, Inside, Last

3x(2x) = 6x²

3x(-4) = -12x

3(2x) = 6x

3(-4) = -12

6x² -12x + 6x-12

Combine like terms

-12x + 6x = -6x

6x² - 6x - 12 is your answer

hope this helps
