Question

If $a + 2b + c$ then the roots of the equation $\left| 3x^{2} + 12x + 6 \right| = 5x + 16$ are.

• A. Complex
• B. Real and unequal
• C. Real and equal
• D. One real and one imaginary

Answer 1

Answer: (B)

Real and unequal

Answer 2

Given equation is $\alpha - k,\beta - k,$

Put $\frac{B^{2} - 4AC}{b^{2} - 4ac}$, $x ^ { 2 } - 6 x + 4 = 0$ $\left( \frac{a}{A} \right)^{2}$

Put k = 3, $x^{2} + px + q = 0,p = 1,q = - 2$i.e., Roots are real and unequal.
