If (1)/((ax+b)(cx+d))+(A)/(ax+b) + (B)/(cx+d) then show that (1)/((ax+b)^(2)(cx+d))=(A)/((ax+b)^(2))+(AB)/(ax+b)+(B^(2))/(cx+d) .

If (1)/((ax+b)(cx+d))=(A)/(ax+b) + (B)/(cx+d) then show that (1)/((ax+b)^(2)(cx+d))=(A)/((ax+b)^(2))+(AB)/(ax+b)+(B^(2))/(cx+d) .

The coefficient of x^(n) in 1+(ax+b)+((ax+b)^(2))/(2!)+((ax+b)^(3))/(3!)+....

If (1)/((ax+b)(cx+d))=(A)/(ax+b)+(B)/(cx+d) then (1)/((ax+b)^(2)(cx+d))=

Solve the following quadratic equation for x.x^(2)-4ax-b^(2)+4a^(2)=0

A circle with radius |a| and center on the y- axis slied along it and a variable line through (a,0) cuts the circle at points P and Q. The region in which the point of intersection of the tangents to the circle at points P and Q lies is represented by y^(2)>=4(ax-a^(2))(b)y^(2) =4(ax-a^(2))(d)y<=4(ax-a^(2))

In the product of (2x^(2)+4x+7)(ax^(2)-4x-b), the coeffiecient of x^(4) is 6 and that of x is 4 .Find a and b.

Solve 4x^(2)-4ax+(a^(2)-b^(2))=0.

x^(2)-2ax-(4b^(2)-a^(2))=0
