1. 4x2 - 4x
= 4x(x - 1)
2. 3ax + 12x - 9
= 3(ax + 4x - 3)
3. 6xy + 2xy2 - 8x2
= 2x(3y + y2 - 4x)
4. -4ay + 10a - 8a2y
= -2a(2y - 5 + 8ay)
5. 10x3 - 8ax2
= 2x2(5x - 4a)
6. 3(x - y) - 6a(x - y)
= (3 - 6a)(x - y)
= 3(1 - 2a)(x - y)
7. 5(x + 2) + 8y(x + 2)
= (5 + 8y)(x + 2)
8. 3x(x - 1) - 6y(1 - x)
= 3x(x - 1) + 6y(x - 1)
= (3x + 6y)(x - 1)
= 3(x + 2y)(x - 1)
9. 4x(2x - 1) + 6(2x - 1)
= (4x + 6)(2x - 1)
= 2(2x + 3)(2x - 1)
10. 3x2(x + 3) - 6x(3 + x)
= 3x2(x + 3) - 6x(x + 3)
= (3x2 - 6x)(x + 3)
= 3x(x - 2)(x + 3)
1: \(4x^2-4x=4x\left(x-1\right)\)
2: \(3ax+12x-9=3\left(ax+4x-3\right)\)
3: \(6xy+2xy^2-8x^2=2x\left(3y+y^2-4x^2\right)\)
