Concept:Expand the product and subtract the second term, then combine like terms.Explanation:First, expand (x+y)(2x−3y+z):x⋅2x=2x2, x⋅(−3y)=−3xy, x⋅z=xz,y⋅2x=2xy, y⋅(−3y)=−3y2, y⋅z=yz.So the expansion is 2x2−3xy+xz+2xy−3y2+yz.Combine like terms: −3xy+2xy=−xy. So we have 2x2−xy−3y2+xz+yz.Now subtract (2x−3y)z=2xz−3yz.So the expression becomes 2x2−xy−3y2+xz+yz−2xz+3yz.Combine xz−2xz=−xz and yz+3yz=4yz.Final simplified expression: 2x2−xy−3y2−xz+4yz.Rewrite −xz as −zx. This matches option A.Answer:Option A: 2x2−xy−3y2+4yz−zx.
