Answer 1

EXPLANATION.

→ √3x² + 11x + 6√3 = 0.

By using middle term split, we get.

→ √3x² + 9x + 2x + 6√3 = 0.

→ √3x ( x + 3√3 ) + 2 ( x + 3√3 ) = 0.

→ ( √3x + 2 ) ( x + 3√3 ) = 0.

Option D is correct answer.

More information.

(1) = D > 0 or [ b² - 4ac > 0 ]

Roots are real and unequal.

(2) = D = 0 Or [ b² - 4ac = 0 ].

Roots are real and equal.

(3) = D < 0 or [ b² - 4ac < 0 ].

Roots are imaginary.

(4) = Discriminant = D = b² - 4ac.
