Subtract -4x^2y-y^3 " from " x^3 +3xy^2-x^2y .

Subtract: x^2-3x y+7y^2-2 from 6x y-4x^2-y^2+5

Subtract : 5y^(4) - 3y^(3) + 2y^(2) + y - 1 from 4y^(4) - 2y^(3) - 6y^(2) - y + 5

Subtract: (-2y^(2)+(1)/(2)y-3) om 7y^(2)-2y+10

" (2) "11x+15y=-23" & "7x-2y=20

Subtract 3x-4y-7z from the sum of x-3y+2z and -4x+9y-11z

Using division show that 3y^(2)+5 is factor of 6y^(5)+15y^(4)+16y^(3)+4y^(2)+10y-35

Write each of the following statement by using appropriate grouping symbols: (a) The sum of x+y\ a n d\ 2x y-3x+2y is subtracted from x y-x+ydot (b) The subtraction of x+y-3 from 3x-2y+9 is subtracted from the sum of 4x+3y-9 and 2x-y+zdot (c) The subtraction of y-1\ from x is added to 3y and its difference from y\ is subtracted from xdot
