Question

OR
If the roots of the equation (a?+b) x2+2 (bc-ad)x+e?+d? =0 are equal, show that
a\b =c\d​

Answer 1

Answer:

the roots of quadratic equation (a² + b²) x² + 2 (b c – a d) x + (c² + d²) = 0 are real and equal, then how to show that a c + b d = 0? ... How do I solve, if the roots of ax^2 + bx + c=0 are w, m and the roots of Ax^2 + Bx +C =0 are w-k, m-k then ((B^2-4AC) / (b^2-4ac)) is equal to?
