若|P+2|与q²-8q+16互为相反数,分解因式(X²+y²)-(pxy+q)=?若|P+2|与q²-8q+16互为相反数,分解因式(X²+y
若|P+2|与q²-8q+16互为相反数,分解因式(X²+y²)-(pxy+q)=?
若|P+2|与q²-8q+16互为相反数,分解因式(X²+y²)-(pxy+q)=?
若|P+2|与q²-8q+16互为相反数,分解因式(X²+y²)-(pxy+q)=?
|P+2|>=0
q²-8q+16=(q-4)^2>=0
|P+2|与q²-8q+16互为相反数
则P+2=0 P=-2
(q-4)^2=0 q=4
(X²+y²)-(pxy+q)
=x^2+y^2+2xy-4
=(x-y)^2-2^2
=(x-y-2)(x-y+2)
