问：等等还有这两题噢谢谢

答：(4m+1)(3m-2)+2(2m-1)(-3m+4)=12m^2-8m+3m-2+2*(-6m^2+8m+3m-4)=12m^2-5m-2-12m^2+22m-8=17m-10

问：可以了吗

答：(6h+k-2)(2h-3)-(4h-3k)^2=12h^2-18h+2hk-3k-4h+6-(16h^2-24hk+9k^2)=12h^2-18h+2hk-3k-4h+6-16h^2+24hk-9k^2=-4h^2+26hk-18h-3k-4h+6-9k^2

答：可以了

答：(6h+k-2)(2h-3)-(4h-3k)^2=12h^2-18h+2hk-3k-4h+6-(16h^2-24hk+9k^2)=12h^2-18h+2hk-3k-4h+6-16h^2+24hk-9k^2=-4h^2+26hk-18h-3k-4h+6-9k^2=-4h^2+26hk-22h-3k+6-9k^2

答：明白了吗？亲
