Question

please solve this question for me..​

Answer 1

Step-by-step explanation:

use the formula b^2 - 4 a c = 0

where b = 2mc, a= 1 + m^2, c = c^2 - a^2

(2mc) ^2 - 4 * (1 + m^2) * (c^2 - a^2) = 0

4m^2c^2 - 4 (c^2 - a^2 + c^2 m^2 - a^2 m^2) = 0

4(m2c2 - c2 + a2 - c2m2 + a2m2) = 0

-c2 + a2 + a2m2 = 0

c2 = a2 + a2m2

c2 = a2 (1 + m2)
