Question

subtract the sum of x 2 - 5 X Y + 2 xy-3xy from the sum of 6xy-8xy-y2 and 2xy-2y2-x2

Answer 1

HERE IS YOUR ANSWER

=x^2-5xy+2xy-3xy
By combining like terms we get
=x^2-5xy+2xy-3xy
=x^2-3xy-3xy=-6xy
=x^2-6xy.
now sum of 6xy-8xy-y^2 + 2xy-2y^2-x^2.
By combining like terms we get
=6xy-8xy+2xy-y^2-2y^2-x^2
=-3y^2-x^2.
Now subtract the sum of bothe terms
=x^2-6xy from -3y^2-x^2
=-3y^2-x^2 +x^2-6xy
combining like terms we get
=-3y^2-x^2+x^2-6xy
= -3y^2-6xy.
