*(2x+1)²+2x+1= (2x+1)(2x+1+1)= (2x+1)(2x+2)= 2(x+1)(2x+1)
*3(2x-3)²-2(2x-3)= (2x-3)(3(2x-3)-2)= (2x-3)(6x-9-2)= (2x-3)(6x-11)
* (x+4)(3x+4)-x-4= (x+4)(3x+4)-(x+4)= (x+4)(3x+4-1)= (x+4)(3x+3)= 3(x+1)(x+4)
* (3x+7)(2x+1)+(x-4)(-2x-1)= (3x+7)(2x+1)-(x-4)(2x+1)= (2x+1)(3x+7-(x-4))
= (2x+1)(3x+7-x+4)= (2x+1)(2x+11)
