[tex]A = (3x+1)(5x-2)\\ A = 15x^2-6x + 5x - 2\\ A = 15x^2 - x-2\\\\ B = (4x-2)(3x-5)\\ B=12x^2 - 20x - 6x+10\\ B = 12x^2-26x+10\\\\ C =(3x-2)^2\\ C = 9x^2 - 12x+4[/tex]

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
