संकल्पना:

यदि   है, तो A की सारणिक निम्न दी गयी है: |A| = (a­11 × a22) - (a12 - a21).

यदि   है, तो A की सारणिक निम्न दी गयी है:

|A| = a11 × {(a22 × a33) - (a23 × a32)} - a12 × {(a21 × a33) - (a23 × a31)} + a13 × {(a21 × a32) - (a22 × a31)}

गणना:

⇒ 2x2 + 8x - 4 = 0

ax2 + bx + c = 0 के साथ समीकरण  2x2 + 8x - 4 = 0 की तुलना करने पर, हमें a = 2, b = 8 और c = - 4 प्राप्त होता है।
