Question

D^{2} \times 1 - 2 - 1 \times D^{2} \times 1 - 2 - 2 D^{2} \times 1 - 2 - 3 D^{2} \times 1 - 2 - 4 D^{2} \times 1 - 2 - 5 D^{2} \times 1 - 2 - 6 D^{2} \times 1 - 2 - 7

Simplify the expression

- 20 D^{2} - 21

Show Solution

D_{1} = - \frac{105}{10} i, D_{2} = \frac{105}{10} i

Alternative Form

D_{1} \approx - 1.024695 i, D_{2} \approx 1.024695 i
