Answer:
[tex]5\,x\,y\,(-x+2-3y)[/tex]
Step-by-step explanation:
Always proceed by first extracting all common factors to all terms:
Notice that the factors: 5, x, and y are present in all terms, so we can extract them from the trinomial:
[tex]-5x^2y+10xy-15xy^2\\5\,x\,y\,(-x+2-3y)[/tex]
Now, the trinomial left (-x+2-3y) cannot be factored out, so then factoring is complete.
