Question

what should be subtracted from xy²-x²y²+x²y to get -5xy²-2x²y²-7x²y?​

Answer 1

Let 'k' be subtracted from xy²-x²y²+x²y to get -5xy²-2x²y²-7x²y

So,

xy²-x²y²+x²y - k = -5xy²-2x²y²-7x²y

xy²-x²y²+x²y -(-5xy²-2x²y²-7x²y) = k

xy²-x²y²+x²y +5xy²+2x²y²+7x²y = k

6xy²+x²y²+8x²y = k

Therefore 6xy²+x²y²+8x²y has to be subtracted from xy²-x²y²+x²y to get

-5xy²-2x²y²-7x²y.

Hope it helps!
