Question

3. From the sum of x2 + x + 1 and x2 - x + 1,
subtract - X2 - x + 1.
4. How much larger is 13x2 - 7y2 than 6x2 - 9y2?
5. What should be added to 2x2 + xy + 2y2 to
obtain 3x2 + 5xy?
6. What must be subtracted from 2x2 - xy + 5y2
to obtain - 5x2 - 3xy - 2y2?
7. If P = 2x2 + 3xy + 3xy - 5y2,
Q = - 5x2 - 4x²y + 2xy + 3y2 and
R = - 3x2 - x²y + 5xy –
xạy + 5xy - 2y2, show that
P + Q - R = 0.
