Question

find determinant of 3x^2-2x-7=0​

Answer 1

Answer:

6x-2

Step-by-step explanation:

Answer 2

Answer:

88

Step by step explanation:

We know that,

For quadratic equation ax²+bx+c=0  <-----General Form

Determinant,

D=b²-4ac

Given equation,

3x²-2x-7=0

Comparing given equation with general form, we get

a = 3

b = -2

c = -7

So,

Determinant of Given equation = (-2)²-4×3×(-7)

                                                    = 4 - (-84)

                                                    = 4+84

                                                    = 88

Hence,

Determinant of 3x²-2x-7=0 = 88
