Subtract: (i) -8xy from 7xy (ii) x^(2) from -3x^(2) (iii) (x - y) from (4y - 5x) (iv) (a^(2) + b^(2) - 2ab) from (a^(2) + b^(2) + 2ab) (v) (x^(2) - y^(2)) from (2x^(2) - 3y^(2) + 6xy) (vi) (x -y + 3z) from (2z - x - 3y)

Subtract : 5x^(2)-3xy -7y^(2) from 3x^(2)-xy-2y^(2)

Subtract 5x^(2)-4y^(2)+6y-3 from 7x^(2)-4xy+8y^(2)+5x-3y

Subtract 5x^(2) -4y^(2) +6y -3 from 7x^(2) -4xy +5y^(2) +5x -3y

Subtract : 7xy + 5x^(2) - 7y^(2) + 3 " from " 7x^(2) - 8xy + 3y^(2) - 5

Subtract: (i) 5a + 7b - 2c from 3a - 7b + 4c (ii) a - 2b - 3c from -2a + 5b - 4c (iii) 5x^(2) - 3xy + y^(2) from 7x^(2) - 2xy - 4y^(2) (iv) 6x^(3) - 7x^(2) + 5x - 3 from 4 - 5x + 6x^(2) - 8x^(3) (v) x^(3) + 2x^(2) y + 6xy^(2) - y^(3) from y^(3) - 3xy^(2) - 4x^(2) (vi) -11 x^(2) y^(2) + 7xy - 6 from 9x^(2) y^(2) - 6xy + 9 (vii) -2a + b + 6d from 5a - 2b - 3c

Add the sum of 5x^(2)-2y^(2)+1 and 3x^(2)-y^(2) to the product of 4x+y and 2x-3y

Simplify the following : 2x^(2) + 3y^(2) - 5xy +5x^(2) - y^(2) + 6xy - 3x^(2)
