If two of the sides of a parallelogram are represented by `ax^2+2hxy+by^2=0" and "pq+qy=1` is one of its diagonals, prove that the other diagonal is `y(bp-hq)=x(aq-hp)`.

If the lines ax^2+2hxy+by^2=0 be two sides of a parallelogram and the line lx+my=1 be one of its diagonal, show that the equation of the other diagonal is y (bl-hm)=x(am-hl).

If the lines ax^2+2hxy+by^2=0 be two sides of a parallelogram and the line lx+my=1 be one of its diagonal, show that the equation of the other diagonal is y (bl-hm)=x(am-hl).

If the lines ax^2+2hxy+by^2=0 be two sides of a parallelogram and the line lx+my=1 be one of its diagonal, show that the equation of the other diagonal is y (bl-hm)=x(am-hl).

If the lines ax^2+2hxy+by^2=0 be two sides of a parallelogram and the line lx+my=1 be one of its diagonal, show that the equation of the other diagonal is y (bl-hm)=x(am-hl).

The equations of the sides of a parallelogram are x = 2, x = 3 and y = 1, y = 5. Equations to the pair of diagonals are

The adjacent sides of a parallelogram are 2x^(2)-5xy+3y^(2)=0 and one diagonal is x + y + 2 = 0. Find the vertices and the other diagonal.

If the adjacent sides of a parallelogram are 2x^(2)5x+3y^(2)=0 and one diagonal is

If 2x^(2)+3xy-2y^(2)=0 represents two sides of a parallelogram and 3x+y+1=0 is one of its diagonals, then the other diagonal is

Two sides of a parallelogram having equation 4x+5y=0 and 7x+2y=0 . One of the diagonal is 11x+7y=9 . Then the other diagonal will surely passes through
