Solution steps

- 4 - 12

- 12 = 2 - 3

= - 4 \cdot 2 - 3

- 4 = 2 i

= 2 i 2 - 3

- 3 = 3 i

= 2 i 23 i

Multiply the numbers:

2 \cdot 2 = 4

= 4 i 3 i

Apply exponent rule:

aa = a^{2}

ii = i^{2}

= 4 i^{2} 3

= 43 i^{2}

Apply imaginary number rule:

i^{2} = - 1

= 43 (- 1)

Multiply the numbers:

4 (- 1) = - 4

= - 43

0 + 2

2 x^{3} - 25 x^{2} + 53 x - 30

48 x

\frac{2 x ^{2} + x}{2 x - 2} + \frac{x - 4}{2 x - 2}

\frac{1}{2} \times \frac{5}{6}
