[" 4.) Show that "x=-(bc)/(ad)" is a solution of the quadratic equation "],[ad^(2)((ax)/(b)+(2c)/(d))x+bc^(2)=0]

The roots of the equation (a^(2)+b^(2))x^(2)-2(bc+ad)x+(c^(2)+d^(2))=0 are equal if

If alpha and beta are the roots of the equation ax^(2)+bc+c=0 then the sum of the roots of the equation a^(2)x^(2)+(b^(2)-2ac)x+b^(2)-4ac=0 is

If alpha and beta are the roots of the equation ax^(2)+bc+c=0 then the sum of the roots of the equation a^(2)x^(2)+(b^(2)-2ac)x+b^(2)-4ac=0 is

(a^(2)-b^(2)-c^(2)+d^(2))^(2)-4(ad-bc)^(2)

Solve the following the quadratic equation by applying the quadratic formula(viii) abx^2+(b^2-ac)x-bc=0

If the quadratic equation alpha x^(2)+beta x+a^(2)+b^(2)+c^(2)-ab-bc-ca=0 has imaginary roots then

Using quadratic formula,solve the following equation for x:abx^(2)+(b^(2)-ac)x-bc=0

If f(x)=(ax+b)/(cx+d'),ad-bc!=0 is inverse of itself then
