Question

The discriminant of the quadratic equation 3/2x2 - 4x - 5 = 0 i

Answer 1

Answer:

D=46

Step-by-step explanation:

$\frac{3}{2} {x}^{2} - 4x - 5 = 0$

$a = \frac{3}{2} \: \: \: \: \: \: \: \: b = - 4 \: \: \: \: \: \: \: \: \: \: \: \: c = - 5$

D=b²-4ac

$\: \: = {( - 4)}^{2} - 4 \times \frac{3}{2} \times ( - 5)$

$16 - 2 \times 3 \times - 5$

$16 + 30$

$46$

D=46
