Question

Still timed. More math needing help with, i'll double points and mark brainliest! 1. (y - 6) (y + 3) 2. (4x - 5) (x - 7) 3.(3x - 2) ( 4x - 1)

Answer 1

Answer:

1) (y-6) (y+3)

=> $y^2+3y-6y-18$

=> $y^2-3y-18$

2) (4x-5) (x-7)

=> $4x^2-28x-5x+35$

=> $4x^2-33x+35$

3) (3x - 2) ( 4x - 1)

=> $12x^2-3x-8x+3$

=> $12x^2-11x+3$

Answer 2

Answer:

1. y² - 3x - 18

2. 4x² - 33x + 35

3. 12x² - 11x + 2

Step-by-step explanation:

All we do with these questions are expanding the factored binomials. Use FOIL:

1. y² + 3y - 6y - 18

y² - 3y - 18

2. 4x² - 28x - 5x + 35

4x² - 33x + 35

3. 12x² - 3x - 8x + 2

12x² - 11x + 2
