Question

XII. If the quadratic equation (1 + a2 )b2x2 + 2abcx + (c2 - m2) = 0, in x has equal roots, prove
That c2 = m2 (1 + a2)​

Answer 1

Answer:

Step-by-step explanation:

for equal roots the discriminant must be zero

D = 0 ;

acc. to your equation A = (1+a2)b2       and B = 2abc and C = (c2 - m2)

from D = 0;

$B^{2} - 4AC = 0$
