因式分解(1) 2x2-x (2)x2-16y2 (3)9a2-24ab+16b2
因式分解(1) 2x2-x (2)x2-16y2 (3)9a2-24ab+16b2

因式分解(1) 2x2-x (2)x2-16y2 (3)9a2-24ab+16b2
1) 2x2-x=x(2x-1)
(2)x2-16y2=((x=4y)(x-4y)
(3)9a2-24ab+16b2
=((3a-4b)²

1.
2x^2-x
=x(2x-1)
2.
x^2-16y^2
=(x+4y)(x-4y)
3.
9a^2+24ab+16b^2
=(3a+4b)^2

1.2x2-x =x(2x-1)
2.x2-16y2 =(x+4y)(x-4y)
3.9a2-24ab+16b2=(3a-4b)^2
