3ax-6ay-8by+4bx

The equation of the parabola whose vertex is (a,0) and the directrix has the equation x+y=3a is x^(2)+y=3xy+6ax+10ay+7a^(2)=0x^(2)-2xy+y^(2)-6ax+10ay+7a^(2)=0x^(2)-2xy+y^(2)+6ax+10ay+7a^(2)=0 None of these

ax-ay=2;(a-1)x+(a+1)y=2(a^(2)+1)

Divide: x^(2)-5x+6byx-3 (ii) ax^(2)-ay^(2)byax+ay

Prove that the circles x^(2)+y^(2)+2ax+ay-3a^(2)=0andx^(2)+y^(2)-8ax-6ay+7a^(2)=0 touch each other.

Factorize each of the following expressions: x^(2)-2ax-2ba+bx(2)x^(3)-2x^(2)y+3xy^(2)-6y^(3)abx^(2)+(ay-b)x-y(4)(ac+by)^(2)+(bx-ay)^(2)

Two circles x^(2) + y^(2) + ax + ay - 7 = 0 and x^(2) + y^(2) - 10x + 2ay + 1 = 0 will cut orthogonally if the value of a is

Two circles x^(2) + y^(2) + ax + ay - 7 = 0 and x^(2) + y^(2) - 10x + 2ay + 1 = 0 will cut orthogonally if the value of a is
