(D) The given equation is $(3x - 14)^2 = 0$.Expanding this,we get $9x^2 - 84x + 196 = 0$.Comparing this with the standard quadratic equation $ax^2 + bx + c = 0$,we have $a = 9$,$b = -84$,and $c = 196$.The discriminant $D$ is given by the formula $D = b^2 - 4ac$.Substituting the values,$D = (-84)^2 - 4(9)(196)$.$D = 7056 - 7056 = 0$.Alternatively,for any quadratic equation of the form $(px + q)^2 = 0$,the roots are equal,which implies the discriminant $D$ is always $0$.
