If the roots of `ax^2+bx+c=0 and px^2+qx+r=0` differ by the same quantity, then `(b^2-4ac)/(q^2-4pr)`

If the roots of the equation x^(2)-bx+c=0 and x^(2)-cx+b=0 differ by the same quantity then b+c is equal to

If the ratio of the roots of x^(2)+bx+c=0 and x^(2)+qx+r=0 is same then

If the roots of the equation ax^2+bx+c=0 differ by K then b^(2)-4ac=

If the roots of the equation x^(2)+px+q=0 and the roots of the equation x^(2)+qx+p=0 differ by the same quantity,then the value of p+qis((A)-148.9)6(B)-2(C)-4(D) none

If 'alpha and beta are roots of ax^(2)+bx+c=0 ,and roots differ by k then b^(2)-4ac=

If alpha and beta are roots of ax^(2)+bx+c=0 ,and roots differ by k then b^(2)-4ac=

If a + b ne 0 and the roots of x^(2) - px + q = 0 differ by -1, then p^(2) - 4q equals :

If alpha , beta are the roots of ax^(2) +bx+c=0, ( a ne 0) and alpha + delta , beta + delta are the roots of Ax^(2) +Bx+C=0,(A ne 0) for some constant delta , then prove that (b^(2)-4ac)/(a^(2))=(B^(2)-4AC)/(A^(2)) .

If the ratio of the roots of ax^2+2bx+c=0 is same as the ratio of the roots of px^2+2qx+r=0 then (i) b^2/(ac)=p^2/(qr) (ii) b/(ac)=p/(qr) (iii) b^2/(ac)=q^2/(pr) (iv) b/(ac)=q^2/(pr)
