Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Correctसही है
(12x^2+x-6=(3x-2)(4x+3)), so (x=\frac{2}{3},-\frac{3}{4}) is correct. In exams, change signs carefully from factors.(12x^2+x-6=(3x-2)(4x+3)), इसलिए (x=\frac{2}{3},-\frac{3}{4}) सही है। परीक्षा में गुणनखंडों से संकेत सावधानी से बदलें।
