(p-4)(p+1)+3p=?(p-4)(p+1)+3p=?(p-4)(p+1)+3p=?(p-4)(p+1)+3p=p²-3p-4+3p=p²-4=(p+2)(p-2)(p-4)

(p-4)(p+1)+3p=?
(p-4)(p+1)+3p=?

(p-4)(p+1)+3p=?
(p-4)(p+1)+3p
=p²-3p-4+3p
=p²-4
=(p+2)(p-2)

(p-4)(p+1)+3p
=p²-3p-4+3p
=p²-4
=(p+2)(p-2)

(p-4)(p+1)+3p=(p^2)-4=(p-2)(p+2)

(p-4)(p+1)+3p=p2-3p-4+3p=p2-4
p2是p的平方,不好打上去。

(p-4)(p+1)+3p
=p²-3p-4+3p
=p²-4
=(p+2)(p-2)

(p-4)(p+1)+3p=p2-3p-4+3p=p2-4

你是毛凤不?

(p-4)(p+1)+3p=(p^2)-4=(p-2)(p+2)
