因式分解(p+2q)^2-2(p+2q)(p+3q)+(p+3q)^2因式分解(p+2q)^2-2(p+2q)(p+3q)+(p+3q)^2因式分解(p+2q)^2-2(p+2q)(p+3q)+(p+

因式分解(p+2q)^2-2(p+2q)(p+3q)+(p+3q)^2
因式分解(p+2q)^2-2(p+2q)(p+3q)+(p+3q)^2

因式分解(p+2q)^2-2(p+2q)(p+3q)+(p+3q)^2
(p+2q)^2-2(p+2q)(p+3q)+(p+3q)^2
=(p+2q-p-3q)²
=(-q)²
=q²

(p+2q)^2-2(p+2q)(p+3q)+(p+3q)^2
=【(p+2q)-(p+3q)】²
=q²

(p+2q-p-3q)^2
