Answer 1

ANSWER :

2x ( x-4 ) 3 ( x-4 ) = 6

2x² - 8x + 3x - 12 = 6

2x² - 5x - 12 = 6

2x² - 5x - 12 - 6 = 0

2x² - 5x - 6 =

2x² + ( - 5x ) + ( - 6 ) = 0

( ax² + bx + c = 0 )

Answer 2

Step-by-step explanation:

(2x + 3) (x - 4) = 6

2x² - 8x + 3x - 12 = 6

2x² - 5x - 12 = 6

2x² - 5x - 12 - 6 = 0

2x² - 5x - 18 = 0

2x² + 4x - 9x - 18 = 0

(2x - 9) (x + 2) = 0

x = 9/2 or -2
