A=(x-2)[(2x+6)-(3x+1)]
A=(x-2)(2x-3x+6-1)
A=(x-2)(-x+5)
B=a^2-b^2
B=[(3x-1)-(x+3)][(3x-1)+(x+3)]
B=(3x-x-1-3)(3x+x-1+3)
B=(2x-4)(4x+2)
B=2(x-2)*2(2x+1)
B=4(x-2)(2x+1)

A= (2x+6)(x-2) - (x-2)(3x+1)
=(X-2)(2X+6-(3X+1))
=(X-2)(2X+6-3X-1)
=(X-2)(-X+5)
B= (3x-1)² - (x+3)²
=(3X-1-X-1)(3X-1+X+3)
=(2X-2)(4X+2)
=2(X-1)(4X+2)
=4(X-1)(2X+1)
