Question

oneplus m square into X square + 2 m c x + c square minus A square is equal to zero has equal roots so that she square is equal to a square into 1 + m square for equal roots B squared minus 40 is equal to zero to MC square she is square - 4 into 1 + 1 square into c square minus A square is equal to zero

Answer 1

(1 + m 2)x 2 + 2 mcx + c 2 - a 2 = 0 has equal roots ⇒ b2 - 4ac = 0 ⇒ (2 mc)2 - 4(1 + m2)(c2 - a2) = 0 ⇒ 4m2c2 - 4(c2 - a2 + m2c2 - m2a2) = 0 ⇒ 4m 2c 2- 4c 2 + 4a 2 - 4m 2c 2 ...
