A= (3x + 1)(5x - 2)
A= 15x² - 6x + 5x - 2
A= 15x² - x - 2

B=(4x - 2)(3x - 5)
B= 12x² - 20x - 6x + 10
B= 12x² - 26x + 10

C=(3x - 2)²
C= 9x² - 12x + 4
A=(3x + 1)(5x-2) A= 15x² -6x + 5x - 2 A= 15x² - x - 2
B= (4x -2) (3x-5) B= 12x² -20x- 6x+10 B= 12x² -26x +10
B= (4x - 2)(3x - 5 ) B= 12x² - 20x - 6x + 10 B= 12x² - 26x + 10
C= ( 3x - 2 )² C = 9x² -12x + 4
