It is given that; the roots of (a 2 b 2) x 2 − 2 b (a c) x (b 2 c 2) = 0 are equal. let us consider a quadratic equation a x 2 b x c = 0, a ≠ 0. so, the discriminant of this equation is, b 2 − 4 a c. when the roots of a quadratic equation are equal, then the discriminant is zero. X² 2ax a² b² c² = 0. a , b , c ∈ r. to prove: roots of the equation are always real. if the standard quadratic equation, ax² bx c = 0. then discriminant is given by, d = b² 4ac. from given equation, a = 1 , b = 2a , c = a² b² c². d = ( 2a)² 4(1)(a² b² c²) = 4a² 4a² b² c² = b² c² . since d > 0.

If ad ≠ bc, then prove that the equation (a 2 b 2) x 2 2 (ac bd) x (c 2 d 2) = 0 has no real roots. the given equation is (a 2 b 2)x 2 2 (ac bd)x (c 2 d 2) = 0. we know, d = b 2 − 4ac. thus, d= [2 (ac bd) 2] −4 (a 2 b 2) (c 2 d 2) = [4 (a 2 c 2 b 2 d 2 2abcd)] −4 (a 2 b 2) (c 2 d 2).

If the roots of the equation (a2 b2)x2 − 2(ac bd)x (c2 d2) = 0 are equal, prove that ba = dc. roots are real only when the discriminant d is positive or 0. since d = 4 (ad bc)^2, then roots are real only when ad bc = 0, ie, ad = bc. now, using the quadratic formula we get just one root = (ac bd) (a^2 b^2). The quadratic equation given is a^2x^2 abx b^2 = 0. to find the roots of this equation, we can use the quadratic formula: x = ( b ± √(b^2 4ac)) 2a in this equation, a = a^2, b = ab, and c = b^2. now let's substitute these values into the quadratic formula and simplify: x = ( ab ± √((ab)^2 4(a^2)( b^2))) 2(a^2).
