Step-by-step explanation:

to simplify this, we just have to add all the like terms, ie, all the terms which have the same literal factors. now, we group the like terms.

12xy²+(-4x²y)+16x²y-15xy²

here, the terms (-4x²y) and +16x²y are like.

and 12xy² and -15xy² are also like.

so, we add these two separately.

the first one is -4x²y+16x²y = 12x²y

the second one is 12xy²-15xy² = -3xy²

now, we add the two and we get 12x²y-3xy²
